patches with some tiny fixes for wily and 9libs

I've been hacking on wily some more.  Oh no!!, I hear people
scream.  ;-)  Relax, no more features ... this time.

Patches are against 9libs-1.0 and wily-9libs 0.13.41.


A simple one for 9libs, a typo:

The function error() doesn't terminate debug output to stderr
with a new line, so multiple messages are hard to read.

Compilation with assertions fails because of a misnamed
variable.

I have rewritten text_fd(), since it had a path of execution
where the file descriptors where opened but never closed.

Oh my, here is a new feature after all.  Really it's an old
feature coming back.  It was in wily pre-9libs, and I liked it.
Click in a window or column tag, B21 on Font (in the global
tag) and see the font in the window/column toggle.  It's still
possible to sweep a font name and B21 to choose that font.
Toggle happens when the arg is "", as it is after a click.
