vi with an 8-bit shell

[Simon Brown]

If you use '%' or '#'in a shell-escape, such as
	:!diff % %.orig
then vi will set the high-bit on the substituted filenames. If you use a
shell which passes 8-bit data correctly (such as ksh-i), then you get:
	diff: mumble.c:  Invalid argument
This doesn't happen for sh or csh, of course, since they strip 8-bit data.

See the unix0() function in ex_unix.c.
