I'd certainly be interested in that; I should have done
the same a long time ago.

In response to your previous question, about whether
ENABLE_MULTIBUFFER and NANO_SMALL should be allowed at the
same time, the only problem with doing so is the lack of
toggles in NANO_SMALL; if one wants to insert a file into a
separate buffer one moment and the current buffer the next,
there's no way for one to do that in NANO_SMALL, since the
Meta-F toggle is disabled.

By the way, I know that I haven't yet gotten around to
fixing the null problem (not displaying NULLs in the file as
^@'s); I've been rather busy lately.  However, I'll get to
it eventually.  (I've been thinking of simpler ways to do it
than writing wrapper functions for all string operations on
the data variable in the filestruct; e. g. convert all NULLs
in the string that don't mark the end of the string to
literal "\0" strings, convert all other backslashes
[including user-input ones] to literal "\\" strings so as to
make the process reversible, and have nano store lines in
that format internally, converting them and possibly certain
input strings [such as search strings] back and forth at

One last question, as long as I'm here: would it be possible
to list Ctrl/Meta-Space in the list of shortcuts on the help
screen?  I can take a stab at it, but I'm planning on doing
the null problem fix first (as soon as I have the time to get
to it).
