Actually, the only system I found that the "--" notation didn't work on
was an old legacy SunOS 4.1.4 system we've got (don't ask...)  It did work
on HP-UX 9.05, 10.20, & 11.0, Solaris 2.5.1, 2.6, and 7, and AIX 4.2.1.

To introduce yet another wrinkle (YAW?) trying to remove a file called
"-r" or "-f" or related always gave me the willies.  I got into the habit
of doing a "mv" first:

	mv -- -f bad.f
	rm bad.f

just to make sure I was deleting only the weird file and no others.
