This is a combination of a huge mechanical patch and a few small fixups required to finish the job. They were reviewed separately, but because the server does not build without both pieces, I've merged them together at this time. The mechanical changes were performed by running the included 'fix-region' script over the whole tree: $ git ls-files | grep -v '^fix-' | xargs ./fix-region And then, the white space errors in the resulting patch were fixed using the provided fix-patch-whitespace script. $ sh ./fix-patch-whitespace Thanks to Jamey Sharp for the mighty fine sed-generating sed script. The hand-done changes involve removing functions from dix/region.c that duplicate inline functions in include/regionstr.h, along with their declarations in regionstr.h, mi.h and mispans.h.
