75em may also be a good limit, now that Number even understands such a
selector.

But seeing Tim's examples: before we start tweaking the indentation of
comments by the pretty printer, which would have it insert tabs or spaces
or anything else, better implement that proposal to display comment lines
left-aligned with the opening ", without requiring indentation characters
in the source text. 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.

To leave the comments untouched by the pretty-printer seems reasonable to
me for now.
