Technically correct yes

Right, I was distracted

You're right! (plus the potential trailing spaces)

Here I have to disagree (with you and Junio): the IPATTERN is
case-insensitive only on the "pattern" regex, not the "word_regex"
regex. It can be seen in the macro definition, and a quick test confirm
that (and we can see that the fortran word_regex, for example, bother
with uppercase and lowercase even thought it use IPATTERN).
On the identifier line, I have "A-F" instead of "A-Z" though
