Unless I'm missing something, the \\ doesn't have anything to do with
the end of a word - in the RE above, the \\ at the end of literal
atoms is introducing 'special' characters i.e. \\| indicates an
alternative and \\(...\\) a grouping which allows you to reference
parts of the match with $1, $2 etc. The $ matches the end of the
string your trying to match and is as far as I know the best and only
way to match the end of a string.
