(line-beginning-position -1) actually moves backwards two lines, which
is really unintuitive (BTW it should be brought in line with
forward-line). So with Yidong's fix all standard variables are printed
on a newline. See C-h v fill-column.
The following patch fixes typo in the fix.

Thanks for the catch. I've committed your fix.

I can confirm this in a "C" locale, too:
ESC [ > 0 ; 2 6 1 ; 0 c ESC ] 1 1 ; r g b : 0 0 0 0
/ 0 0 0 0 / 0 0 0 0 ESC \ d s d s RET ESC x ESC p ESC
x v i e w - l o s TAB RET
Are those escape codes registered as typed keystrokes?

See xterm.el:terminal-init-xterm, search for send-string-to-terminal.
In a nutshell, we send special commands to the terminal to find out
about its capabilities.

And it's scarcely worth it to try to remove these characters from
lossage, so feel free to close this bug.

But maybe also p u t s o m e t i n y h i n t i n t o that buffer so
folks know what is going on.
