Re(2): shell bug I reported here a few days ago

[Tim Smith]

Well, I just tried everything on a System III sh.  This is even stranger.
Let 'parent' be a command that prints the result of getppid().
Then the command

	if true
	then
		parent
		parent
		parent
	fi < /dev/null

shows the first two 'parent' commands are run from a subshell, while the
third is run from the main shell!  What IS going on?
