Nope. We need something independent from a scale factor and thus the default font size as pretty-printed format can be checked in. Better use "66 characters", not 75em. No rendering/font properties. For multi-line comments, use the line-break algorithm as in Text >> #withNoLineLongerThan:.

Please read the commentary in
TextStyle >> #compositionWidthForNumChars

That's an excellent point; extra-long lines are really annoying to read in general.

Remember that other thread about whether or not to have line breaks in comments? Somebody posted a screenshot from Dolphin Smalltalk that shows what I am referring to.

Oh, I'm not wanting to have any tabs or spaces inserted - I want the formatting to be live and use the left indent. Shout does all that work to colour (etc) the text so why not use the fact that it detects comments.
