Solution for meta/escape in terminal mode

Wed Apr 25 20:43:46 CEST 2012

Hi Frank,

I just ran a few tests and the problem does only appear to be an issue
under tmux, when I use a bare terminal (rxvt-unicode) everything works
fine.

An example of the problem would be from insert mode quickly pressing ESC k,
which I expect to exit insert mode and move up a line.  Under tmux it
just says "End of buffer" and remains in insert mode.
