Move extents.c to working in byte positions only; fix a bug, extent_detach() src/ChangeLog addition: 2015-03-27 Aidan Kehoe <kehoea@parhasard.net> Fix a small bug, extent_detach(); minimise needless char-byte conversion, extents.c, sticking to byte positions in general in this file. * extents.c: * extents.c (signal_single_extent_changed): Pass byte endpoints to gutter_extent_signal_changed_region_maybe(), buffer_extent_signal_changed_region(). * extents.c (extent_detach): Call signal_extent_changed() correctly, pass both extent endpoints rather than just the byte and character variants of the start. * extents.c (struct report_extent_modification_closure): Do this in terms of byte positions. * extents.c (report_extent_modification_mapper): Use byte positions, only converting to characters when we are definitely calling Lisp. * extents.c (report_extent_modification): Use byte positions in this API, move the byte-char conversion to our callers, simplifying extents.c (it all now works in byte positions). * extents.h: Update report_extent_modification's prototype. * gutter.c (gutter_extent_signal_changed_region_maybe): Use byte positions here, avoids needless byte-char conversion. * gutter.h: Update the prototype here. * insdel.c: * insdel.c (buffer_extent_signal_changed_region): Implement this in terms of byte positions. * insdel.c (signal_before_change): * insdel.c (signal_after_change): Call report_extent_modification() with byte positions, doing the char->byte conversion here rather than leaving it to extents.c. * insdel.h: * insdel.h (struct each_buffer_change_data): The extent unchanged info now describes bytecounts.
