#35 perl regex escape searches

[Ian M. Donaldson]

Regex expressions with \D, \d, \W, \w, \B, \B do not
work even though their counterpart set expressions (eg
[^0-9]) do work.

I have found that regex expressions with \D, \W, \w, \s
returned a page displaying 'Internal server error'. This is
true also with $ (although not .$ -- see bug 539038).
Regex expressions with \S seem to work as expected, while
SOME regex expressions with \d (ie /prp\d/ and /car\d/)
worked as expected, while OTHERS (ie /cdc\d/)
returned 'Internal server error'.
These searches were performed both using Query Builder and
the simple text search tool.
