This is part of the 4.3 BSD csh.. It's invoked by setting the shell
variable 'filec' to something.. The original (Greer) tcsh also
used to do terminal sanity checking when a program exited and set it
back to something normal if it seemed braindamaged in some way. This
was useful, but as Mike Meyer just pointed out: What happened when
you ran stty? Did it set you back afterward? I didn't know the answer
to that question (it was probably kludged), but we're pretty sure
that the 4.3 csh doesn't do that for you.. So the REAL answer is that
4.3 csh doesn't do EVERYTHING tcsh did..
