patch: add support for git delta hunks
When creating patches modifying binary files using "git format-patch",
git creates 'literal' and 'delta' hunks. Mercurial currently supports
'literal' hunks only, which makes it impossible to import patches with
'delta' hunks.
This changeset adds support for 'delta' hunks. It is a reimplementation
of patch-delta.c from git :
http://git.kernel.org/cgit/git/git.git/tree/patch-delta.c
pathcomplete: remove ambiguous entries for sole completion on a directory
Previously, directories were added with the trailing slash and, if there was
only one completion, then another ambiguous entry was created using '.', as
follows:
$ hg rm mer<TAB>
mercurial/./ mercurial//
This was added in
fa6d5c62f3bd (though, some logic existed before that) to work
around bash completion adding a space after the sole entry because we treated
directories and files the same. We no longer do that now so we remove this
unneeded code.
Tests have been updated to match this new behavior.
bash_completion: add global support for -b|--branch
Previously, only -r|--rev was parsed globally which meant 'hg push -b <tab>'
would try to complete a path instead of a branch.
