Follow-up Comment #7:

I committed your first patch.  It is the simpler fix and in practice is
unlikely to ever be a problem.  Users who are constructing patters, like
'\>\w', where there would be a difference don't understand regular
expressions.

I also changed the documentation to remove reference to '\b' which is the
backspace character.

If there is ever a need, we could use lookahead assertions to exactly match
'\<' and '\>'.

Matlab  =>   PCRE


\<   =>   \b(?=\w)
\>   =>   \b(?<=\w)
