Package: emacs

With the current trunk on GNU/Linux:

TERM=xterm-vt220 emacs -Q -nw

gives an error at startup:

tty-run-terminal-initialization: Wrong type argument: number-or-marker-p, nil


Emacs 23.3 works fine with this TERM.

The error comes from terminal-init-xterm at line 542, where version is nil.

I also noticed a pointless check at line 511:

(when xterm-extra-capabilities

This code is already inside a "(when xterm-extra-capabilities" at line 488.

What kind of beast is xterm-vt220?  How is it different from xterm?

It's aterm:

I've been using it for ages.

Can you show all the responses of this terminal to the queries that
xterm.el sends to it?  It looks like it responds to some, but not to
others, and the combination is not one of those xterm.el expects.

The differences seem significant enough to justify a separate
configuration.

Thank you for fixing that with rev 104578 through 104575 (104575 was the
essential fix).

Thanks for catching that too, plus your other style fixes and
simplifications.

I disagree with replacing `when' with `if' in the case of just one
clause, which you did in several places.  Rather than simplifying the
code, it complicates reading it IMO.  Since `when' is a macro I think
any performance gains are minor.

Glenn, can you reply to this please?  If `when' should be discouraged,
tell me so, otherwise I'm not sure why you changed it.

Oh, sorry. Just personal preference. I don't see the point of using:

(when
  single-form)

since it expands to

(if
  (progn
    single-form))

which seems like a waste of a progn to me. (Maybe the compiler optimizes
it away though, I don't actually know.)

In this case, I think I was just put in an anti-when mood by things of
the form:

(when a
  (when b
   ...))

Comments in byte-opt indicate that it does. So the compiled coded ought
to neither know nor care if the source used when or if.

OK, thanks for explaining.  I'll keep happily using `when' :)
