Pattern obsolete in grepview plugin?

[George Syron]

  While fixing the duplicates problem in the grepview plugin, I saw this:
http://gitorious.org/kdevelop/kdevplatform/blobs/master/plugins/grepview/grepjob.cpp#line205

The things that came to my mind:
"%s" is not a regexp, so why use QRegExp? The only answer is: people may 
search for "duplicate" with the pattern "%s\%s", which effectively 
searches for "duplicate%s", but the escaped %s is not handled, so the 
QRegExp should become "[^\\]%s" if I remember right.

Are other patterns planned? If so, which would that be?
Thanks for answers.
