[Nano-devel] [PATCH] input: erase next word if ctrl is held when pressing delete

[Marco Diego Aurélio Mesquita]

Attached patch is an updated version of the previous one. Main
differences are that now it should be handling ctrl+del, working
correctly or without complaining ("Unknown sequence", with or without
-K) in the terminals I tested: GNOME Terminal, urxvt, xterm and a
virtual linux console.

For added info, here are the results of the tests I ran:
