Oops.  No, although I haven't seen the released 4.3BSD source yet, I
don't think "limit" was ever added to "sh" at Berkeley.  The "sh" I used
on my VAX until recently wasn't vanilla BSD.  I was not careful enough
when I verified the "limit" command on the VAX here.

I could have sworn that I verified this feature was in the vanilla Sun 2
shell before I posted my followup.  I am embarrassed to admit that I was
a source of misinformation.
