Yes, and more generally, the BRE and ERE tests could check for
spelling of diagnostics, and grep could use the same spellings in
both the regex and the dfa cases.  This could be done in two
more patches, I suppose.  Things could get a little tricky there,
though, as the spellings might differ depending on whether grep
is built --with-included-regex.  Possibly dfa.c should not use
its own diagnostic strings at all, and just use regex's.  But
this is turning into a bigger project....

Anyway, for now I pushed the fix, with your cfg.mk patch added.
