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.

bash_completion: add global support for -B|--bookmark Previously, only -r|--rev was parsed globally which meant 'hg push -B <tab>' would try to complete a path instead of a bookmark.

bash_completion: change --rev if-else block into a case Again, this doesn't change behavior but does make it easy to add cases in the next patch.

bash_completion: simplify if-else logic There is no change in functionality here but this makes refactoring this later easier.

bash_completion: add _hg_branches for list of branches

bash_completion: add -B|--bookmark support for strip

bash_completion: add completion for deleting a shelve

bash_completion: use correct command for listing shelves Previously, _hg_shelves used the unshelve command to list current shelves. This is actually the wrong command. The correct usage is 'hg shelve -l' so we use that instead.

bash_completion: remove restriction on bookmark completion Previously, we only completed a bookmark when deleting or renaming a bookmark. Since we can now move a bookmark forward, we drop this restriction.
