test: further fixes to matching for run-tests.py bug

The fix in bac24a8a095a did not fix the full issue, because the extra number
also eat some of the separator space. Since we are already matching arbitrary
number of space, we easily fix the matching.

"""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=@).
