I find <rev>:<path> vs <rev> -- <path> confusing:
| <rev>:<path> | <rev> -- <path>
----------+----------------------+---------------------
git grep | OK | OK
----------+----------------------+---------------------
git show | OK | <path> ignored
----------+----------------------+---------------------
git log | no output | OK
----------+----------------------+---------------------
Neither syntax always does what I expect. If git show <rev> -- <path>
honored <path> then I could use that syntax consistently.
Sorry for going on a tangent. Does it seem reasonable to handle <path>
in git-show(1) as a UI convenience?

Yes, reparsing the name is ugly and I hoped to get feedback with this
RFC. Thanks for the quick review!
