I approve this without cshjunkietests since it makes the code simpler.  The
other reason is that the while list; { ... } syntax always worked.

Below is the documentation.  I do not know much about nroff so if something
is wrong in it, tell me.  I'll be away till thursday.  Than I'll release
3.0-per2.  I've already fixed most signal related bugs and made ulimit bash
compatible.
