* src/nano.c (move_to_filestruct) - Update the data in 'mark_begin'
when mark and cursor are on the same line. This avoids a segfault
after M-A, right, M-T, left, ^K, or a hang when the left is left out.
2014-02-22 Benno Schulenberg <bensberg@justemail.net>
* src/nano.c (main) - Add two conditions on ENABLE_NANORC.
* src/files.c (close_buffer, do_insertfile) - Likewise.
