[PATCH] glossary.texi additions

[Doug Evans <dje at sebabeach dot org>]

Hi.

This patch adds a few entries to glossary.texi and cleans it up a bit.
I'll check it in in a few days if there are no objections.

btw, I'm going through the entire manual, prior to releasing 1.1.

	* doc/glossary.texi: Add ifield, iformat, sformat, insn.
