And this bug has already been reported (twice) to Debian, as it turns
out:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=584191
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=586134

No resolution in either bug stream although suggestions do include
[A-Za-z] and [[:alpha:]].

I have simply edited /usr/bin/texi2dvi (but need to do this on all of
my other systems) and hope that next time it is upgraded the bug will
have been fixed...
