Funny, I did not even register those double quotes, just saw the
extra set of braces and then kicked myself, just like a solution
to many perl issues when you need an extra layer of eval.

I did this -
preexec () { print -Pn
"\033k\033\134\033k[${1[1,12]}..${1[-6,$]}]\033\134" }

How would I do arbitrary string searching and replacement in the `$1'?
Like to grab the top level domain from a URL or whatever.

Currently my window captions look like this:

[s asteri..vvvvv -c]  1 [vim .screenc..aptio]  4 [vim food..2013.txt]

Nice, but still a bit lame.
