They hypothesis behind this change is that the undo is
undoing an edit that came before, not the temporary edit
that appears in insert-close-paren. So, when there are
no edits happening (ie when fixup? is #f) then don't
undo. This is only a hypothesis because we were not able
to find a small code sequence, outside of DrRacket to
cause the bad behavior, so possibly there is really more
going on here.
Thanks to Nadeem Abdul Hamid for finding this fix.

The code to draw a border has to determine the widget's position
within the drawing window. Gtk 3.0 has a function to provide that
transformation, but Gtk 2.0 doesn't seem to have one, and it seems
that the transformation implemented in `racket/gui' wasn't right.

The goal is to better handle situations like this one:
╔═══╗
║ - ║
╚═══╝
where the hyphen should not change.

guard more of the filesystem manipulations with
handlers and log errors instead of letting them
be raised and show up as internal errors

There appears to be no way to make `on-demand' work right for the
Unity window manager's global menu bar, since there's no notificiation
when the menu bar is clicked. We approximate the correct behavior
by calling `on-demand' when a containing frame loses the keyboard
focus, which might be because the menu bar was clicked; that may be
too late (because the menu has already been shown), but it should
work most of the time.
Closes PR 13347.
Relevant to PR 13395, but DrRacket will have to change to work
around the remaining limitations of `on-demand'.

it only looks left and right at hyphens and only
up and down at pipes, etc. This better handles the
case where you have something like this:
+--------------+
| (<= a-x b-y) |
+--------------+
Before this commit, it would have adjusted the hypens
inside the identifiers

adjust the way it changes characters so it
doesn't change them when they are already the right
thing (this means set-modified is not always called
and also improves performance in the case that little
changes in a big diagram)
original commit: 5a9c5f681b11d563275f7672c3af5160bb68113c
also clean up the code a bit (make sure the h? argument to
set-label-visible is really a boolean and make some of the
long lines narrower)

I had it all backwards: DrRacket went from "increment" to Greek
capital delta (which makes a lot more sense).
original commit: 490a474e0e4b92af8956cab13d885349053a3973
This change was prompted by the change to DrRacket's "\Delta"
to produce the Unicode "increment" character.

This didn't matter much before but now that
paren colors have interesting alpha components,
things look bad when it is ignored!
