Revision Log
Removed this annoying \n from DPRINTF output. DPRINTF behaves now like usual printf. Just for fun, i decided to exercice my regexp skills: for i in `find . -name "*.c"` ; do sed s/'\(DPRINTF(XVID_DEBUG.*\)"\([^"]\+[^\\][^n]\)"\(.*\)$'/'\1"\2\\n"\3'/g $i > $i.tmp; mv $i.tmp $i done Nice isn't it ? It just adds a \n to every DPRINTF call that was relying on old behavior (automatic trailing \n).
