I'm having problems using e?grep 1.5 on a Vax 8650 (berkeley-unix)
with the regards to \b.  The manual says that \b matches the
empty string at the beginning of a word, but I can't seem to get
it to work:

% grep '\bto\w*' prog.c

I'm trying to match the functions toupper, tolower, etc., in a
program.  However, grep doesn't seem to match anything, when
there are definitely instances of such functions in the
program.  Additionally, GNU Emacs works correctly when given the
same regexp.  Is this a bug or just a misunderstanding?
