6502bench/SourceGenWPF/MainController.cs
Andy McFadden 99b484df4c Implement long-comment editing 
We can now Edit Long Comment and Edit Header Comment.

Changing the number of lines in a long comment exposed a bug in the
display list update.  Fixed.

Running the WinForms version trashed the column widths, which exposed
the fact that the default column widths were set too narrow.  Fixed.

On an unrelated note, hitting undo/redo quickly will sometimes leave
you scrolled to the bottom of the code list.  Some sort of command-
handling race in the WPF framework?  (Not fixed.)
