bug #57397: unbinding ^/ is ineffective, and binding ^/ does not unlist ^_

Fixed in git, commit 9e3fca40.

(It also unbinds ^Space when ^@ gets bound, because also those two are synonymous.  Also ^` is synonymous with those two, but nano does not yet allow to bind ^`.  For symmetry I will make it so, though.  But will not go as far as recognizing also ^2 to ^8 and ^~.)

When putting for example this at the end of your nanorc:

  bind ^/ nextword main

then running nano and typing ^G, and then searching for M-G, it stills says: "^_     (M-G)     Go to line and column number".  But when you type ^_ (in the edit window), it jumps to the next word.

In short, when a bind or unbind of ^/ is done, it should unbind all relevant occurrences of ^_ too.

To reproduce, put this at the end of your ~/.nanorc:

  unbind ^/ main

Now run nano, and type ^/.  They keystroke still works (invoking the Go-to-line prompt).

The problem is that the unbind loop (rcfile.c around line 500) searches through the key strings, not the key codes, and by default the canonical synonym of ^/ is bound: ^_.  So in fact unbinding ^/ should unbind ^_.

Checking for this specific synonym wil be ugly.  It would be easier (and quicker) if we could check against the keycode, but at that point the corresponding keycode hasn't been determined yet...

Bug exists since version 4.6, where the ^/ synonym was introduced.
