richedit: (8/8) empty text should result in a scroll range of 0. Tests for this behavior.

[Alex Villací­s Lasso]

See bug #12311. A further patch that attempts to generalize this to text 
not in need of scrolling causes a regression with another app, so I am 
not sending that one yet.

Changelog:
* richedit: empty text should result in a scroll range of 0.
* Tests for this behavior.

perl -e '$x=2.4;print sprintf("%.0f + %.0f = %.0f\n",$x,$x,$x+$x);'
