592d0d6c9a files: trying to open a non-existent file will never succeed 
If it would, the returned file descriptor would make nano crash,
because the corresponding stream has not been opened.  And when
returning zero instead (as the code did originally), nano would
open an empty buffer, although it claims to be reading the file.

In short: I think this is a leftover of an attempted fix of
https://savannah.gnu.org/bugs/?25297, from commit 2823c99.

3cc561e36e input: distinguish <Shift+Home> from <Home> on an rxvt terminal 
That is: when --rebindkeypad is in effect -- without this option
they were already getting distinguished.

0333b87ad7 input: distinguish <Alt+Left> from <Alt+Right> on an rxvt terminal 
Both would jump a word to the left -- now each jumps a word in the
proper direction.

9c2e270b3e softwrap: initialize 'editwincols' early, for computing the number of wraps

to know the width of the screen to be able to (roughly) place the target
line in the center of the screen.

8ba57cf87b input: don't return zero when some function is completely unbound 
Returning a zero would mean returning a ^Space -- the keycode that
by default is bound to the Next-Word function.  So, unbinding the
keys to which the modified Arrow keys are hard bound would cause
the latter ones to mysteriously jump to the next word.

This partially fixes https://savannah.gnu.org/bugs/?49058.
