Fixed in git, commit 51c9f727, by returning the first byte immediately (when available).

The problem is that get_code_from_plantation() always returns ERR after putting some of the keycodes of a string bind into the keystrokes buffer.  It should return ERR only when there are no more keycodes left in the string bind (which will normally only occur when the string bind was defined as empty, which is useless); in all other cases it should not put the first of the keycodes into the keystroke buffer but return it immediately.

To reproduce, add this at the end of your .nanorc:

bind M-N "{verbatim}^T{verbatim}^U" main

(where ^T and ^U are literal control codes).

Then run 'nano -xc --mini' and type: M-N

See that a prompt appears and an invalid byte has been entered:

Command to execute: �

Type Enter and see that nano complains:

[ Error: $'\377': command not found ]

Also see that there is an invalid byte in the buffer too.  This byte is 0xFF.

It seems that somehow the {verbatim} function is returning the ERR code instead instead of the next code in the string.  Things work fine when using "^[v" (a literal M-V) instead of "{verbatim}".
