Breno Silva Pinto resolved MODSEC-141.
--------------------------------------

    Resolution: Fixed

The pattern matching operator now support the syntax:

breno
ry|61|n
|41 42 43 44|
function|28|re|28|s,n,r,b,e|29|

This will make ours operator more powerful.

> The @pm operator needs to be able to handle basic characterset patterns like boundaries, whitespace, alpha, numeric, etc.
> Probably need to be all anchors or 1:1 mappings (ie no variable width patterns like \s+).
> PCRE style character class identifiers should be used (ie \b, \s, \S, etc.)
> Need a way to escape them. (ie \\b)
> Need a way to use non-printable characters (ie \x00) and escape them (ie \\x00)
> Need to be possible:
> - \bword\b
> - \b1.2.3.4.5\b
> - \b1.2.3.
> - \bparam\d
> - \b\d\d\d\d-\d\d\d\d-\d\d\d\d-\d\d\d\d\b
