[regex-coach] [:alnum:]

Hi there. First of all great job you've done there with RegEx Coach :)! While I was testing some regular expressions for logcheck (a program to check logfiles e.g. syslog etc. :)), I noticed, that the expression [:alnum:] for alphanumeric characters (used with egrep) isn't recognized correctly. I think it's because CL-PPCRE is used, is that correct? Will there be alnum support in some way in the furure? B.R. Veit Guna
