That would still be different from what we do with simple strings.  I
don't really have a good idea.

title = "These three words"
title = \markup { These three words }

Reasonable expectation to format them the same?  The latter is the same

title = \markup \line { These three words }

So should we deconstruct a line markup and do a wordwrap on it, and a
wordwrap-lines on markup lists, to make a difference?  Wait, this is a
markup-command, it cannot return a list.  So it's wordwrap either way.

So what to do with a markup that isn't a line markup?

title = \markup \italic "This is a string"

Ugh again.
