I made a couple of changes before checking in:

* In libos.tex, I moved the text out of the popen4 function
description, and into the block above the popen2/3/4
definitions.
* In libpopen.text, I moved the text up a bit.
* In popen2.py, I added the text to the functions in the
other block of platforms as well.
