[docs] [issue29315] \b requires raw strings or to be escaped. Update docs with that hint?

R. David Murray added the comment:

One should always use raw strings for regex expressions, and this is already documented in the introduction to the regex module.  Further, in 3.5 using \ in front of characters that aren't special produces a warning, which should reduce the frequency of this mistake.

I don't see that there's anything to do here.
