This has the same trouble as "for f in *.h" -- it works great
when there *are* files matching the pattern, but it does the
wrong thing when there aren't any.

The answer turns out to be, "set the nullglob shell option,
eg shopt -s nullglob". That changes the behavior of glob
expansion: when nullglob is set, "*.h" always expands to
precisely a list of existing .h files in the current directory
(that is, if there aren't any files matching the pattern,
it expands to "" rather than "*.h").

Doubtless this will come back to bite me in some soft-tissue
area in the future, but for now, it works.
