so that these files also depend on m4/getopt.m4.

and configuring a getopt replacement if necessary.

if current start position is in a string or image.
(move_it_vertically_backward): Be sure to move out of strings and
images when moving it2 forward.
(move_it_by_lines): When moving forward, move to next buffer
position if we end up in a string or image. When moving backward,

backward if we end up in a string or image.
(try_cursor_movement): if overlay string spans multiple lines,
move backward to set cursor on start of an overlay string.
