Benno Schulenberg 27aff84f74 syntax: nanorc: paint arguments of 'include' and 'extendsyntax' specially
The path after 'include' is not a regex and does not need to be quoted;
when it's unquoted, colorize it specially, instead of leaving it red.

The syntax name after 'extendsyntax' should be brightgreen, like after
'syntax', but it's better that the subsequent commands have their own
special color.
