I just tried to write additional tests to exercise this in our
config-tests by using `git config --get-urlmatch` with multiple
`http.extraheader`s set. I've been stumped that it still didn't
work correctly with my patch, only the last value was actually
ever returned.
I think that is very much in line with "git config --get" works, and
"--get-urlmatch" being an enhancement of "--get", I would expect
that "--get-urlmatch" to follow the usual "the last one wins" rule.
If you want to see _all_ values for a multi-valued variable, you
would say "git config --get-all". IIUC, there currently is no
"--get-all-urlmatch", but there may need one. I dunno.
