It should support anything nano supports, and nano supports everything except 
for whitespace.

Nano doesn't care if it contains a double-quote.

    syntax nano"rc "..."
    nano -Y 'nano"rc' nanorc.nanorc

As for the escaped quotes, nano should be fixed to require them. Try a regex 
that has a space after a quote.

    color red "[^" ]"
