I'm reopening, because I think this does make sense as a feature
request.  Generally foo.c and foo.h will be related if they are in the
same "project", so probably the user will want the file to be found in
this case.  I think Emacs recently got some kind of "project API" thing,
perhaps that can be used for this?
