Subject: [PATCH] In the last clean-up of this code, the fact that the default
 tty mode information could only be gleaned from the the tty descriptor itself
 was neglected, so never did the tty's default settings get copied from the
 kernel.  Specifically, this caused all manner of ctrl-keys to not work.  Fix
 this by calling dogettytab() in all the proper places, and retrieving the
 terminfo temporarily in dogettytab().
