X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e3c57e9e4802a4c0a103e7c44858a349594a4235;p=thirdparty%2Fsarg.git

Display the offending regular expression if an error is detected

If a regular expression is invalid, the actual regular expression is displayed
in the error message in addition to the error message from libpcre. The user
will know what regular expression failed.
