That seems more confusing that just saying: '*' matches everything but
the path separator ('/'), and whatever it matches on the LHS of the
':' is what it expands to on the RHS. I'm not sure how a typo would
damage anything, but this could always be enabled with
core.refspec.glob_anywhere or some such.
I think regex support is too much:
fetch = some/constant/stuff/(my-proj-[^/]*)/junk/my-proj:refs/remotes/origin/\1
(Which in a git config, I think may need a double-backslash, but I
forget what the config parser does.)
