Hi Martin,
Sorry to be persnickety, but ...

Function name formatting - name on a separate line from the return type.
And yes, I know that the same problem exists for the is_underscoring()
function directly before this one. A patch to fix that formatting is
pre-approved. :-)

Strictly speaking this should be an error return value. Maybe return
INT_MAX ? Or generate an error message and then return 1. This test
will probably never trigger however, so just returning 1 is OK really.
In fact just ignore me on this one...
> + int c2 = *s2++; /* Assumed to be lower case from the caller. */
Assumptions are bad. But testing this assumption does lead to needless
performance penalties. So ignore me on this one too.
But please do fix up the comment formatting.

Similar comment apply here, of course.
Hmm. We really ought to move the code duplicated in pe.em and pep.em into a
single file...
Cheers
Nick
