Agreed, I'm not sure there is any way we can force a uniform commit id
format with the possibility of merging branches.

It seems to me that whoever does the merge has to vouch for the
commits in the branch that gets merged.

Why not put a list on the wiki and ask people to edit.  I'll see what
I can find ...

Seems like it has to come down to policy.  Anyone who wants to merge a
branch needs to make sure it has sane commit ID's first.  Its fairly
easy to track down who merged a commit, so this may require some
enforcement, but people will learn fairly quickly if its enforced.
