Line numbers for soft-wrapped styled text?

[Alex Tweedly]

Hi.

That works for "simple" fields which may contain soft-wrapped lines - 
but it doesn't account for styled text (e.g. where different lines may 
be different font sizes (or even mixed sizes), or where paragraph 
spacing has been set, or .... all the complex kinds of text we can now do.

but for situations where those complexities can be avoided, it is much 
simpler and faster :-)
