Re: git-checkout doesn't seem to respect config from include.path

I think that would be worthwhile, the warning is potentially confusing
though if a bad value is followed by a good value then we will warn 
about the bad value but use the good one.

I dunno.  That is exactly why the new message is crafted to convey:
"you have an entry with an unsupported value in your configuration
file, which you may want to inspect and possibly correct it; in the
meantime we've ignored that entry".  "ignored" is the key word.

If we say "we later found this good value so we'd use it", it may
become confusing, as we'd never issue such a notice for a
last-one-wins variable that do not use any unsupported values, but
we are not doing that, so I think there is no room for confusion.

Completely untested.  The first test that would be interesting to
run is how many tests this changes breaks to gauge how good test
coverage we have ;-)
