Strange "1;2600;0c" sequence in startup (message-mode?)

Strange "1;2600;0c" sequence in startup (message-mode?)

[Jesse Sheidlower]

I have recently been seeing a strange sequence of characters when I
start Emacs up to send a message, either when sending a new message, or
replying to an existing one. I believe that this started when I began to
use message-mode. Typically it will be "1;2600;0c", inserted at the
start of a message, but I have noticed other numbers close to "2600" in
the middle section.

This only happens when I have started typing before Emacs has fully
launched (usually by hitting return once or twice); if I wait for it to
load, I do not get any such sequence. But it does happen very regularly
when

It's been hard to Google for this. Does this ring a bell for anyone? I
have some hooks for message-mode, but nothing that looks like it could
cause this, although I don't know what the sequence represents.

Thanks.

It's the end of an escape sequence.  You're probably using emacs in a
terminal, and there must be a discrepancy between what the terminal is
really, and what declared in the environment variable TERM.  Or perhaps
there's an error in the terminfo (or termcap) database.

It looks more like a response to the "Send Device Attributes" control
sequence.

If you're using gnome-terminal or some other terminal that uses vte,
that's
the likely explanation (can't google on this, since there's no useful
documentation
for vte).

Likewise, it won't be a problem with the terminal description, since
that feature's
only addressed in the (nonstandard) u8 capability, and emacs wouldn't
be using it.

This looks similar to cursor positioning control sequences.  Are you
using Emacs on a character terminal rather than in graphical mode?

Yes, I am--when this happens I'm ssh'd into a Unix shell, and am
interacting with Emacs there, not in an X display.

Er, so what does this mean in terms of trying to fix it? It's a
relatively new phenomenon.

I told you.  Set your TERM environment variable correctly, or correct
the terminfo database on the remote system.
