[Patch] RtL space width bug fix

[Martin Vermeer]

The displayed width of a space on-screen is taken from the wrong
position in the row... but only for RtL text. And thus the row display
is messed up if it contains spaces. Patch fixes this.

I believe this to be correct, but please test. Bug and patch are in
bugzilla: bug 2029.
