I tried adding

    (setq xterm-extra-capabilities nil)

to my ~/.emacs and as at

    GNU Emacs 24.4.1 (x86_64-pc-linux-gnu) of 2014-10-26 on trouble,
    modified by Debian

...I still saw that M-x turned into just x if I typed it while Emacs
was starting (using ALTERNATE_EDITOR= emacsclient -c -t).

I tried using *just* that line as my .emacs,
but emacs started too fast for me to type the M-x. :-)

I don't have a 25.x handy to test with - since 24.4 has
xterm-extra-capabilities I hope it's new enough to be a useful test.

It definitely doesn't happen with just "emacs" instead of
"ALTERNATE_EDITOR= emacsclient -c -t".
