Removed call to FlushPendingNotifications() in SetCaretEnabled() because it causes a reflow during painting. That can cause certain view updates to be dropped on the floor on Linux. Also removed tab characters in SetCaretEnabled(). r=sfraser@netscape.com, a=beppe@netscape.com git-svn-id: svn://10.0.0.236/trunk@72378 18797224-902f-48f8-a5cc-f745e15eee43
