	auspex% cd s5r3_source/cmd/vi/port
	auspex% patch ex_unix.c <nicks_patch
	Hmm...  Looks like a new-style context diff to me...
	The text leading up to this was:
	--------------------------
	|*** port/ex_unix.c.old
	|--- port/ex_unix.c
	--------------------------
	Patching file ex_unix.c using Plan A...
	Reversed (or previously applied) patch detected!  Assume -R? [y] n

S5R3's "ex"/"vi" *already* had the quoting removed....
