Log Message:
Initial import of ce-doc-4.4, from my own PR pkg/15627.
Suggestions from agc. Approved by garbled.

This editor is derived most directly from Dave Conroy's original
MicroEmacs (uEmacs) editor, version 30, and Dan Lawrence's MicroEmacs
v3.6.  Some stuff from mg, version 2a, has also been used.

This package manages the documentation.
