Modified files:
usr.bin/cmp regular.c
Log:
The cmp utility has the questionable feature of using mmap when
comparing regular files. Add a SIGSEGV handler to make its
behavior less surprising when a read error occurs. The handler
does not attempt to distinguish errors from file truncation, but
anyone actively modifying a file while trying to compare it
shouldn't even expect something sane to happen.
