Problem with tag option "ignore"

[Servatius]

When I use [all].ignore.sort={The,A,Les,Le,L',La,Der,Die,Das,Ein,Eine}, "La primavera" is sorted correctly, but "L'estate", "L'autunno", and "L'inverno" are not.

This happens because the articles in the option parameter are matched only if followed by a space. Can this be changed to match at a word boundary (using a RE with \b)?
