That's nice, thank you! It seems to be about 19 % faster than the = previous patch on this particular file, which is not bad at all. Somehow, the delay when inserting a newline (pressing return) at line = 83610 of osprey_reg_map_macro.h becomes longer with the patch. Of course = this is more than compensated by the speed-up in general, but it may be = worth taking a look at. There is also a new and noticeable delay (0.5-1 s) in the very beginning = when scrolling through the file. (This is with the frame sized to show = 41 lines of 80 chars of a window, excluding mode line and echo area.)
