Follow up r16837 replaces sprintf with snprintf to at least ensure we dont go over our length in a modified msg table -- (in the future we should make that a #define or something else practical and clever). The commit should've stopped on this, however as I was to compile I realized my recently-updated osx got rid of my makefile during the update, so I had to download and install it over. and during that download period I've gone over the whole chrif.c file and applied some syntax love to it, or as some of my lovely colleagues would say: I gayed it up.
