What a day.  Is there a reason why rc barfs on a umask greater than
0777?  I have just modifed one of my scripts to protect a temporary
file by doing:

	umask = `{ umask }
	umask 077
	...
	umask $umask

and it now doesn't work properly if I use an escape from vi inside MH,
as MH sets umask to 7177 (quite why I don't know).

sh and sh5 seem to perform a umask (value & 0777), csh and bash give an
error message if the value is > 0777, but ksh goes ahead and does it.
