This is also true of the 4.2 systems around here; unfortunately, that
first "set noglob" doesn't do you any good, as any globbing on `tset ...`
occurs before eval gets to it.  The command "echo `tset ...`" shows you
the arguments that eval actually sees, and they probably aren't what you
want, unless globbing has been turned off.

So, it looks like the mininum we can get away with is
