Maintaining expect (the broken pipe errors)

[Daniel Santos <daniel dot santos at pobox dot com>]

I should probably import this onto my github account.  There doesn't 
appear to be an actual repository for expect at the moment.  There are 
many terrible coding practices employed, potential use of uninitialized 
locals, etc.  I'm going to do some basic cleanup before I dig back into 
trying to find the cause of the child processes unexpectedly terminating 
(while calling an ioctl to change the terminal windows size), which is 
what's causing the broken pipe.
