Fix bug #6161: Wrong cursor position in bidi text.

Browse Source 
If the first character is a separator, we are in RTL text. This character will not be painted on screen and thus we should not count it and skip to the next.

This bug pretty much destroyed cursor placement in RTL text on a row with large gaps.
