Allow git merge ":/<pattern>"jc/want-commit
It probably is not such a good idea to use ":/<pattern>" to specify which commit to merge, as ":/<pattern>" can often hit unexpected commits, but somebody tried it and got a nonsense error message: fatal: ':/Foo bar' does not point to a commit So here is a for-the-sake-of-consistency update that is fairly useless that allows users to carefully try not shooting in the foot.
