Extraneous characters appear after copying characters to buffer

I will preface this by saying that I am not 100% convinced that this is
a tmux issue, as I'm only seeing this in termite[1], and not in xterm.

This only appears when I have split panes. When I copy text to the copy
buffer, odd text appears in the other panes. It does not disappear until
I switch panes (i.e. a ^l redraw of the screen doesn't remove them).

Here[2] is a gif showing this behavior. Like I said, I'm not convinced
100% that it is a tmux issue. If it indeed turns out not to be, I was
hoping to get more specific information to pass on to the termite[1]
developers.

This is from the xterm clipboard escape sequence which tmux will use
when the set-clipboard option is on and TERM is xterm (or, more
accurately: when it sees Ms in terminfo, which we add for xterm in
terminal-overrides).

You can either use the correct TERM for your terminal (which I recommend
anyway) or turn off set-clipboard in tmux.

I set the TERM to screen-256color using the "default-terminal" global
option to get 256-color support. Otherwise I never touch TERM. I only
recently switched to termite as my terminal emulator, before that I used
urxvt and never saw this. I've been using tmux since about 1.1 and
didn't even know about set-clipboard, according to the changelog it
appears to have been added in tmux 1.5. Disabling set-clipboard has
resolved the issue for me.

Thanks!
