Use Scintilla's logic for deciding when to coalesce edit box changes

Scintilla's modification notifications don't expose enough information
to do a very good job of deciding when to group changes with previous
ones, but it does expose when Scintilla thinks undo groups should end,
so just use that.

This should significantly improve the behavior of undo when editing
lines in the edit box.
