patch: handle filenames with trailing spaces
I have no idea if this is *actually* supported by the patch file format, but at
least when reading from a patch file created by running `hg shelve`, it is
written out such that there's a trailing space after the second (`b`) filename.
When we read the patch file, we remove the space before parsing the filenames,
so it doesn't end up matching the other sources of what files are in the shelve.
We observed this internally due to a wrapper around unshelve that called into
patch.changedfiles, but `hg patch` is able to reproduce the issue as well, so
I've included both tests.

"""implements bookmark-based branching (EXPERIMENTAL)
- Disables creation of new branches (config: enable_branches=False).
- Requires an active bookmark on commit (config: require_bookmark=True).
- Doesn't move the active bookmark on update, only on commit.
- Requires '--rev' for moving an existing bookmark.
- Protects special bookmarks (config: protect=@).
