This really is no guarantee that /bin/sh limits itself to a sh-only
subset. On most Linux boxes bash invoked with argv[0] of sh will behave
differently, but still accepts some things which the original sh
wouldn't. Dennis Ritchie has on his site some of the historical man
pages for sh and others; I write to those when I want to be portable.

I did, it calls some psh (what is this? I can't find a man page for it)
to use its builtins, apparently ksh doesn't have these and 15 other
commands that link to this script. How strange.

Just makes me dislike ksh even more ;)
