* gtk/gtktextview.c (gtk_text_view_start_cursor_blink): Apply
patch from Mikael Hermansson to temporarily stop blinking while
the user is using the keyboard to type or navigate.

Also, when blinking, stay on for longer than we stay off. Also,
return from start_cursor_blink if !cursor_visible, to save
checking that flag all over the place before we call
start_cursor_blink.
