revset: rename diff(pattern) to diffcontains(pattern)

Suggested by Augie, and I think it's better name.

  $ hg init t
  $ cd t
  $ echo import > port
  $ hg add port
  $ hg commit -m 0 -u spam -d '0 0'
  $ echo export >> port
  $ hg commit -m 1 -u eggs -d '1 0'
  $ echo export > port
  $ echo vaportight >> port
  $ echo 'import/export' >> port
  $ hg commit -m 2 -u spam -d '2 0'
  $ echo 'import/export' >> port
  $ hg commit -m 3 -u eggs -d '3 0'
  $ head -n 3 port > port1
  $ mv port1 port
  $ hg commit -m 4 -u spam -d '4 0'

pattern error

  $ hg grep '**test**'
  grep: invalid match pattern: nothing to repeat* (glob)
  [1]

invalid revset syntax

  $ hg log -r 'diffcontains()'
  hg: parse error: diffcontains takes at least 1 argument
  [255]
  $ hg log -r 'diffcontains(:)'
  hg: parse error: diffcontains requires a string pattern
  [255]
  $ hg log -r 'diffcontains("re:**test**")'
  hg: parse error: invalid regular expression: nothing to repeat* (glob)

Moved line may not be collected by "grep --diff" since it first filters
the contents to be diffed by the pattern. (i.e.
"diff <(grep pat a) <(grep pat b)", not "diff a b | grep pat".)
This is much faster than generating full diff per revision.

Test for showing working of allfiles flag

  $ cd sng
  $ echo "unmod" >> um

  $ echo "something else" >> new

Existing tracked files in the working directory are searched by default

  $ echo modified >> new
  $ echo 'added' > added; hg add added
  $ echo 'added, missing' > added-missing; hg add added-missing; rm added-missing
  $ echo 'untracked' > untracked
  $ hg rm old

#if symlink
Grepping a symlink greps its destination

  $ rm -f added; ln -s symlink-added added
  $ hg grep '' | grep added
  added:symlink-added

But we reject symlinks as directories components of a tracked file as
usual:

  $ mkdir dir; touch dir/f; hg add dir/f
  $ rm -rf dir; ln -s / dir
  $ hg grep ''
  abort: path 'dir/f' traverses symbolic link 'dir'
  [255]
#endif

But we can search files from some other revision with -rREV

  $ hg grep -r. mod
  um:1:unmod

  $ hg grep --diff mod
  um:0:+:unmod

  $ cd ..

Change Default of grep by ui.tweakdefaults, that is, the files not in current
working directory should not be grepp-ed on

  > tweakdefaults = True
  > EOF
  $ echo "some text">>file1
  $ hg add file1
  $ hg commit -m "adds file1"
  $ hg mv file1 file2

wdir revision is hidden by default:

  $ hg grep "some"
  file2:some text

but it should be available in template dict:

  $ hg grep "some" -Tjson
  [
   {
    "date": [0, 0],
    "lineno": 1,
    "node": "ffffffffffffffffffffffffffffffffffffffff",
    "path": "file2",

    "texts": [{"matched": true, "text": "some"}, {"matched": false, "text": " text"}],
    "user": "test"
   }

--follow with/without --diff and/or paths
-----------------------------------------

For each test case, we compare the history traversal of "hg log",
"hg grep --diff", and "hg grep" (--all-files).

"hg grep --diff" should traverse the log in the same way as "hg log".
"hg grep" (--all-files) is slightly different in that it includes
unmodified changes.
