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.)

This addresses https://savannah.gnu.org/bugs/?62997.

+Each regular expression in a @file{nanorc} file should be wrapped in
+double quotes (@code{""}).  Multiple regular expressions can follow
