It's certainly a good practice to check the return status of each and
every system call. Meanwhile, the mechanism used by ferror() is pretty
good; errors detected by fwrite() or fflush() set a bit that ferror()
can be used to check. And I really don't care when the error is
detected so long as my mail drop doesn't get clobbered.

I suppose one reason my fix wasn't included in mh 6.6 is that I didn't
implement it until a few weeks ago.
