JavaScriptCore uses a modified version of the PCRE library to do its regular
expression matching.  The embedded version is at version 6.4.  Versions 6.5,
6.6, 6.7 and 7.0 have been released since 6.4.

If you have time, please test this expression with the newer versions of pcre
to find out if upgrading will benefit WebKit.  (It's on my mental to-do list to
upgrade the embedded version, but I've been distracted by other shiny objects
like webarchives recently.)

Apple's UTF-16 changes (and Mitz's recent non-null-terminated API changes) to
PCRE really need to be contributed back to the PCRE project so that (some day)
PCRE could be linked to WebKit instead of being embedded in it.
