[pcre-dev] Suggested addition for pcregrep

Hi Philip,

Could you please add an option for naming a file that contains a list of
files to be searched? Possibly --filelist=

Since globbing doesn't work at all when pcregrep is built in some
environments, the user could create a list by piping from the dir command.

The option could also be used to facilitate special searches. E.g., to
look only in the set of files that contained matches for a previous
execution of pcregrep.

Regards,
Sheri
