Hi Eric,

Thanks for having a look.

Huh, good catch. The tests showed up in v2 of the patch [1] and there's
not enough context in the archives to tell whether something was partly
removed from an earlier "v1.5" or partly added but not all the way.

We expect to fail the merge -- and we do, and not because of this msg
thing -- and then we look around a little, but we don't resolve the
merge and make a commit. And from what I can tell, there wouldn't be
much point in making a commit. So I should be able to safely drop this
"dead code" entirely.

FWIW, I find something like `git foo -m "message"` a lot more
intuitive/reasonable than, e.g., `git foo "HEAD"` to signal that here's
a message that could in principle have whitespace, even if this one
doesn't. For all of these, I tried to follow the surrounding style. For
example in t9401, where we do `echo "hi"`. We certainly don't need the
quotes there, but t9401 is very consistent on this and I didn't want to
muddy that unnecessarily.

If we say that "don't use quotes if you don't need to" is a reasonable
thing to strive for, I can drop these in a reroll. I think I'll be
injecting a patch anyway for the "msg" you pointed out in t4200, so I
can certainly tweak this patch to be a bit more aggressive in dropping
unnecessary quotes.

Thanks
Martin
