I was working on testing out some ideas with expanding edit fields
and thought I would check them in, but being a prudent programmer I
checked the functional tests first. Alas, the tests failed, and in
fact the app crashed.
I'll look into the crashes more tomorrow, but thought I'd send this
patch for people to take a look at. It causes the currently-being-
edited field to switch to a 2-line-high, scrolling text field while
it has focus. It also sets the tooltip for the field if the text is
longer than the display width.
II'm only using for the item's title and description right now to
test it out (e.g. the "Welcome to Chandler" and "Open Source
Applications Foundation" text in the default item).
In case the mailing list software strips Mime attachments, it can
also be found at http://chandler.tnir.org/rae-expano-diffs.txt
