Done, now extended POSIX regex is used.

I'd personally suggest going ERE instead of PCRE simply because ERE can be done natively with no extra dependencies than the usual ones for C code (libc, etc) wherease PCRE would require you to install your distribution's PCRE package that is not installed by default on Debian or ArchLinux or CentOS.

The FILTER command only accepts POSIX BRE (basic regular expressions as in ed(1), which the POSIX manpage itself calls 'obsolete'), thus not providing much of the usual matching functionality (e.g. alternatives separated by '|' etc.). It would be better to switch to ERE (extended POSIX regexes) or PCRE instead.
