reverse search is all fucked up.

2007/07/15:
sometimes you don't get search-as-you-type (and have to hit C-s an extra time
to see anything).

2007/07/12:
sometimes searching seems to save the wrong cursor position, or not overwrite
the previously used one, and you end up finding matches *before* your search
started.

2006/07/04:
undo/redo should probably show you what is being undone (i.e. by jumping to that
region of code).

2006/07/04:
undo/redo is mostly fixed, but there are still occasionally problems, which seem
to relate to pasting in multiple lines and cursor positioning.
