If I have a /bin/sh script that contains:

	while :
	  do
		# various commands
	  done

Under Ultrix 1.2, Sun3.2, HP-UX, Apollo Domain/IX, and NCR SystemV.2, if
I "sh -nv" the script, it hangs after printing out the "done" line.  Is this
a (mis)feature?

csh doesn't have this problem with scripts containing "infinite" loops.
