Attached are some proposed patches which should improve the performance of grep -P when applied to binary files, among other things. I have some other ideas for boosting performance further but thought I'd publish these first.
I pushed those patches, along with the attached further patches to fix up some porting glitches and bugs I encountered in subsequent testing. I plan to follow up soon on Bug#18454 with more performance-related patches in this area.
