Benno Schulenberg e7491920fd docs: explain how to include a double quote plus space in a nanorc regex
As double-quote-plus-space indicates the end of a regular expression
in a nanorc file, the inclusion of this combination *in* a regular
expression requires breaking the juxtaposition of the two, which
can be achieved by putting either of them between square brackets.

(It can also be achieved by preceding the space with a backslash,
which is shorter, but... the above method is more symmetrical.)
