Fix a segfault and functional error in c_gets(),
which is used for extended command input and for vi search mode.
It could be triggered by typing one or more characters, then pressing
backspace once (functional error: the character was deleted from
the screen, but not from the edit buffer) or a few more times than
characters had been entered (segfault).
OK czarkoff@. Also checked by Christos Zoulas.
