D7: editor multi-cursor support
Add secondary_cursors field to Editor with insert_char_multi, delete_back_multi, delete_forward_multi methods. Right-to-left processing ensures position shifts don't corrupt earlier insertions. 7 new tests: add/clear, all_positions, insert, delete_back, delete_forward, unicode, duplicate-add.

Finally, the \fB\-m\fR (\fB\-\-merge\fR) option causes diff3 to do the merge internally
|
||||
and output the actual merged file. For unusual input, this is more
|
||||
robust than using ed.

If a FILE is '\-', read standard input.

Exit status is 0 if successful, 1 if conflicts, 2 if trouble.
