I've found what appears to be a bug in diff version 1.7.  Please unshar
these two short files and see if you get CORRECT results for:

	diff -c one two

but INCORRECT results for:

	diff -c two one

Also, if the -c flag is not used, a "diff two one" fails in a slightly
different manner than the context diff.

I'm using a VAX 11/780, running 4.3BSD.  I tried both Berkley's cc & Gnu's
gcc for compilation -- both fail in the same way.

Thanx for your time.
