GNU Emacs release dates

[Ben Wing]

Here is what I've written in the XEmacs Internals manual concerning GNU
Emacs:

Can anyone add to this?

@cindex Great Usenet Renaming

As described above, Emacs began life in the mid-1970's as a series of
editor macros for TECO, an early editor on the PDP-10.  In the early
1980's it was rewritten in C as a collaboration between Richard
M. Stallman (RMS) and James Gosling (the creator of Java); its extension
language was known as @dfn{Mocklisp}.  This version of Emacs-in-C formed
the basis for the early versions of GNU Emacs and also for Gosling's
Unipress Emacs, a commercial product.  Because of bad blood between the
two over the issue of commercialism, RMS pretty much disowned this
collaboration, referring to it as "Gosling Emacs".

At this point we pick up with a time line of events. (A broader timeline
is available at @uref{http://http://www.jwz.org/doc/emacs-timeline.html,
``Emacs Timeline''}.)

@strong{NOTE}: Sometimes there are two release dates listed below.  In
this case, the first one is the date listed in the source code, and
the second one is when the official announcement was made on
Usenet. (Sometimes, one or the other of the dates is missing, and then
the date below reflects the only existing one.)
