This patch implements Vim motions. The VimMotion class will accept
keycodes from the editing engine to build up a motion, and will
signal when a motion is complete via VimMotion::is_complete(). The
editing engine can then call VimMotion::get_range() to obtain a
TextRange object which can be used to perform operations on the text,
or VimMotion::get_position() to obtain a TextPosition which is the
new position of the cursor after the motion.
Currently, the following motions are supported:
- h/j/k/l, regular Vim line and character movements
- 0/^/$, start/end of line and start of non-blank
- w/e/b/ge, word-related movements
- W/E/B/gE, WORD (anything non-blank) versions of the above motions
- gg/G, document related movements
- t/f, to/find character
All motions except gg/G accept a number prefix to repeat the motion that
many times.
This patch updates insert, normal and visual modes to use this motion
system for movement.
