* src/nano (precalc_multicolorinfo): Do not match the ^ anchor when
looking further on in a line. This prevents an end="^$" from being
sometimes mistakenly matched. Fix inspired by Savannah bug #27708.
2014-05-17 Benno Schulenberg <bensberg@justemail.net>
* doc/syntax/json.nanorc: New file, originally from Aapo Rantalainen,
but edited, extended, and improved. See Savannah patch #7410.
