Okay, this is weird.  I posted this to tech-pkg but now understand it 
to be an error on this particular build of -current on this Alpha, 
dated Sep. 30.  There were getopts changes to /usr/bin/patch in August 
that seem to cause the fuzz option to fail on this 2.0H machine.

SCARAB) patch --version
Patch version 2.0, patch level 12u8

SCARAB) ls -laF `which patch`
-r-xr-xr-x  1 root  wheel  72093 Sep 30 14:03 /usr/bin/patch*

SCARAB) patch -F0
patch: unrecognized option `-F0'

Data points:

1.  -Fn works with the same patch version 12u8 on 2.0F Alpha and x86 
userlands from June.
2.  Every other option works, only -Fn fails.
3.  Building manually in src/usr.bin/patch doesn't fix the error.
4.  Mandoc, command-line help, and the source code indicate -Fn should 
be there.

What should I look at rebuilding?
