tests: fix portability of sed usage in test-mq

on some platform (Mac OS X and Solaris, at least), to insert new text
line, sed function 'i' should be followed by:

  - backslash('\'),
  - new-line,
  - text to be inserted and
  - new-line

GNU sed on Linux can recognize both previous and new ones as same
modification request.

in addition to it, this patch avoids to use '-i' option for sed,
because it is not so portable, as noted in WritingTests wiki page.

Create the repo with a couple of revisions of both large and normal
files, testing that status correctly shows largefiles and that summary output
is correct.

  $ hg init a
  $ cd a
  $ mkdir sub
  $ echo normal1 > normal1
  $ echo normal2 > sub/normal2
  $ echo large1 > large1
  $ echo large2 > sub/large2
  $ hg add normal1 sub/normal2

  $ hg sum --large

  branch: default
  commit: (clean)

Commit preserved largefile contents.

  $ cat normal1

  $ cat large1

  $ cat sub/normal2

  $ cat sub/large2

Remove both largefiles and normal files.
 
  $ hg remove normal1 large1
  $ hg status large1
  R large1
  $ hg commit -m "remove files"
  Invoking status precommit hook
  R large1
  R normal1
  $ ls
  sub
  $ echo "testlargefile" > large1-test
  $ hg add --large large1-test
  $ hg st

  $ hg rm large1-test

  $ hg st
  A large1-test
  $ hg forget large1-test
  $ hg st
  ? large1-test
  $ rm large1-test

Copy both largefiles and normal files (testing that status output is correct).

  $ hg cp sub/normal2 normal1
  $ hg cp sub/large2 large1
  $ hg commit -m "copy files"
  Invoking status precommit hook
  A large1
  A normal1
  $ cat normal1

  $ cat large1

Test moving largefiles and verify that normal files are also unaffected.

  $ hg mv normal1 normal3
  $ hg mv large1 large3
  $ hg mv sub/normal2 sub/normal4
  $ hg mv sub/large2 sub/large4
  $ hg commit -m "move files"

Test archiving the various revisions.  These hit corner cases known with
archiving.

  $ hg archive -r 0 ../archive0
  $ hg archive -r 1 ../archive1
  $ hg archive -r 2 ../archive2
  $ hg archive -r 3 ../archive3
  $ hg archive -r 4 ../archive4

Commit corner case: specify files to commit.

  $ cd ../a
  $ echo normal3 > normal3
  $ echo large3 > large3
  $ echo normal4 > sub/normal4
  $ echo large4 > sub/large4
  $ hg commit normal3 large3 sub/normal4 sub/large4 -m "edit files again"
  Invoking status precommit hook

  M sub/normal4
  $ cat normal3
  normal3
  $ cat large3
  large3
  $ cat sub/normal4
  normal4
  $ cat sub/large4
  large4

One more commit corner case: commit from a subdirectory.

  $ cd ../a
  $ echo normal33 > normal3
  $ echo large33 > large3
  $ echo normal44 > sub/normal4
  $ echo large44 > sub/large4
  $ cd sub
  $ hg commit -m "edit files yet again"
  Invoking status precommit hook
  M large3
  M normal3

  $ cat large4

Committing standins is not allowed.

  $ cd ..
  $ echo large3 > large3
  $ hg commit .hglf/large3 -m "try to commit standin"
  abort: file ".hglf/large3" is a largefile standin
  (commit the largefile itself instead)

Corner cases for adding largefiles.

  $ echo large5 > large5
  $ hg add --large large5
  $ hg add --large large5
  large5 already a largefile
  $ mkdir sub2
  $ echo large6 > sub2/large6
  $ echo large7 > sub2/large7
  $ hg add --large sub2
  adding sub2/large6 as a largefile (glob)
  adding sub2/large7 as a largefile (glob)
  $ hg st
  M large3
  A large5
  A sub2/large6
  A sub2/large7

Test "hg status" with combination of 'file pattern' and 'directory
pattern' for largefiles:

  $ hg status sub2/large6 sub2
  A sub2/large6
  A sub2/large7

Config settings (pattern **.dat, minsize 2 MB) are respected.

  $ echo testdata > test.dat
  $ dd bs=1k count=2k if=/dev/zero of=reallylarge > /dev/null 2> /dev/null
  $ hg add
  adding reallylarge as a largefile
  adding test.dat as a largefile

Test that minsize and --lfsize handle float values;
also tests that --lfsize overrides largefiles.minsize.
(0.250 MB = 256 kB = 262144 B)

  $ dd if=/dev/zero of=ratherlarge bs=1024 count=256 > /dev/null 2> /dev/null
  $ dd if=/dev/zero of=medium bs=1024 count=128 > /dev/null 2> /dev/null
  $ hg --config largefiles.minsize=.25 add
  adding ratherlarge as a largefile
  adding medium
  $ hg forget medium
  $ hg --config largefiles.minsize=.25 add --lfsize=.125
  adding medium as a largefile
  $ dd if=/dev/zero of=notlarge bs=1024 count=127 > /dev/null 2> /dev/null
  $ hg --config largefiles.minsize=.25 add --lfsize=.125
  adding notlarge
  $ hg forget notlarge

Test forget on largefiles.

  $ hg forget large3 large5 test.dat reallylarge ratherlarge medium
  $ hg commit -m "add/edit more largefiles"
  Invoking status precommit hook
  A sub2/large6
  A sub2/large7

  $ hg st

Purge with largefiles: verify that largefiles are still in the working
dir after a purge.

  $ hg purge --all
  $ cat sub/large4
  large44
  $ cat sub2/large6
  large6
  $ cat sub2/large7
  large7

Test addremove: verify that files that should be added as largfiles are added as
such and that already-existing largfiles are not added as normal files by
accident.

  $ rm normal3
  $ rm sub/large4
  $ echo "testing addremove with patterns" > testaddremove.dat
  $ echo "normaladdremove" > normaladdremove
  $ hg addremove
  removing sub/large4
  adding testaddremove.dat as a largefile
  removing normal3

test for pattern matching on 'hg status':
to boost performance, largefiles checks whether specified patterns are
related to largefiles in working directory (NOT to STANDIN) or not.

  $ hg init statusmatch
  $ cd statusmatch

  $ mkdir -p a/b/c/d
  $ echo normal > a/b/c/d/e.normal.txt
  $ hg add a/b/c/d/e.normal.txt
  $ echo large > a/b/c/d/e.large.txt
  $ hg add --large a/b/c/d/e.large.txt
  $ mkdir -p a/b/c/x
  $ echo normal > a/b/c/x/y.normal.txt
  $ hg add a/b/c/x/y.normal.txt
  $ hg commit -m 'add files'
  Invoking status precommit hook
  A a/b/c/d/e.large.txt
  A a/b/c/d/e.normal.txt
  A a/b/c/x/y.normal.txt

(1) no pattern: no performance boost
  $ hg status -A
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt
  C a/b/c/x/y.normal.txt

(2) pattern not related to largefiles: performance boost
  $ hg status -A a/b/c/x
  C a/b/c/x/y.normal.txt

(3) pattern related to largefiles: no performance boost
  $ hg status -A a/b/c/d
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt

(4) pattern related to STANDIN (not to largefiles): performance boost
  $ hg status -A .hglf/a
  C .hglf/a/b/c/d/e.large.txt

(5) mixed case: no performance boost
  $ hg status -A a/b/c/x a/b/c/d
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt
  C a/b/c/x/y.normal.txt
