linenoise: Ctrl-A/E overloaded in multi-line mode.

* linenoise/linenoise.c (edit_move_sol): If the cursor
is already at the beginning of a line, then move it
to the start of the buffer.
(edit_move_eol): If the cursor is at the end of the
line, then move it to the end of the buffer.
This also fixes a bug: previously, if the cursor was
at the end of the line already, it moved to the end
of the following line.

* txr.1: Documented.
