Reality check.  I tested it.  It was not up to par.  You seem to say
that one should only be allowed to test it, not change it.

Oh for heavens sake, don't you read this list?

Start something like
(the point being to remove terminal-related variables)
and then, from a tty, start

emacsclient -t

This does not work.

There _is_ no ChangeLog file for multi-tty yet, and I _did_ create a
CVS log entry.

I _did_ post the patch to the list.

There was breakage _before_.  And I asked several times whether the
people who could not follow my report had used multi-tty HEAD from
Emacs CVS.

Fine, this is for now the end of my involvement with the multi-tty
branch.  I am reverting the change and deleting my checked-out copy.
There is no sense bothering with code that people don't want to see
any work done on.
