Made KBDD script work on Linux

This seems to be a very specific way to get it to work using the properties of how
kbdd echoes to screen. This is not a general solution.

I am not sure why the general solution that works on OS X (the version of script
used is different from the one on Linux) does not work on Linux.

I have posted a question on StackOverflow

See #6.
