Ah, thanks. This makes grepping through the raw deltas less useful than a full text diff, because you could have a patch like < int xyzy(char * bla) > int xyzzy(char * bla) which is in fossil just a 'copy off1, len1; insert "z"; copy off2, len2;' patch. No way to find xyzzy as string in any insert. -- Bernd Paysan "If you want it done right, you have to do it yourself" http://bernd-paysan.de/
