In this example (out of an Excel file) there are some segments with many blanks.
In this case, wouldn't it make sense to have a line wrap instead of very wide source segment (what means that parts of the soruce segment cannot be read without scrolling from side to side)? Or asked in another sense: Why isn't there any line wrap here?
I suppose this kind of line wrap usually does not play any role for words (with the exception of Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch, of course),
The latest update 7 forces the wrapping without any horizontal scrollbar.
