Indeed :-)

There is a locale-independent range spec for regexps:

      [:alpha:]

would match the indicated class in any locale. See the egrep man page
for more of these. I sent some mail to address@hidden suggesting
this, so we'll see.

I also found out to my surprise from the previously posted bug-texinfo
thread, that the ASCII characters between 'Z' and 'a' are (or were) legal
drive letters, but the assumption is that nobody would be so foolish as
to use them any more, so not checking for them is OK.
