patch: handle 0 context lines (diff.unified=0) when parsing patches

Previously, if there were no context lines, we would just keep updating the
ranges and the hunk, but not actually storing the hunk (just overwriting it each
time).  Thus a diff like this:

    $ hg diff --config diff.unified=0
    diff --git a/bar b/bar
    --- a/bar
    +++ b/bar
    @@ -1,0 +2,1 @@ 1
    +change1
    @@ -3,0 +5,1 @@ 3
    +change2

would come out of the parser like this (change1 is lost):

    bar:
    @@ -3,0 +5,1 @@ 3
    +change2

This had some really weird side effects for things like commit --interactive,
split, etc.

Test update.requiredest
  $ cd $TESTTMP
  $ cat >> $HGRCPATH <<EOF
  > [commands]
  > update.requiredest = True
  > EOF
  $ hg init repo
  $ cd repo
  $ echo a >> a
  $ hg commit -qAm aa
  $ hg up
  abort: you must specify a destination
  (for example: hg update ".::")
  [255]
  $ hg up .
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ HGPLAIN=1 hg up
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg --config commands.update.requiredest=False up
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ cd ..

Check update.requiredest interaction with pull --update
  $ hg clone repo clone
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd repo
  $ echo a >> a
  $ hg commit -qAm aa
  $ cd ../clone
  $ hg pull --update
  abort: update destination required by configuration
  (use hg pull followed by hg update DEST)
  [255]

  $ cd ..

update.requiredest should silent the "hg update" text after pull
  $ hg init repo1
  $ cd repo1
  $ hg pull ../repo
