fmt::fatal - exit with 255
fmt::fatal returning 255 will more reliably indicate a generic error
condition.
there are cases where the required exit status of a program is not
binary between a generic error condition and success. among POSIX
utilities, 0 always indicates success; however, 1 does not always
indicate a generic error. values >127 are always specified to be a
generic error except in the commands command, env, nice, nohup, time,
and xargs.
