It's not FreeBSD's default, it's POSIX's and has been the default
behaviour of diff since forever (i.e. before -c or -u had even been
invented); it is also the default behaviour of diff on every version of
Linux I've ever used as well and probably every unix-like box you can
get your hands on. Backwards compatibility *is* a wonderful thing.
-u is a newbie to the diff world of options and is the strongly
*preferred* way of providing patches, and probably not just for
FreeBSD. It's generally the easiest for humans to read and the best for
general use, though -c isn't that hard either and can sometimes be
easier to comprehend.
