The application referenced in bug #709 (Perfect! TextEdit) is one string
of crashes. At least three distinct crashes are caused by bugs in
richedit. Tests for this change will come with a following patch.
* Only notify selection change when selection has actually changed from
previous notification. Otherwise, redundant and early notifications are
sent to apps that do not expect them. Fixes crash #1 with Perfect! TextEdit.
perl -e '$x=2.4;print sprintf("%.0f + %.0f = %.0f\n",$x,$x,$x+$x);'
