scm/define-markup-commands.scm:3765: * \\translate #'(2 . 3) translate
Probably this example should place the translated markup relative to
music, rather than in a line of \markup; otherwise, someone might
experiment with this and conclude that \translate cannot move things to
the left.

I agree that it should be fine to have a line of markup space a
\translated piece so there is no overlap.  We have never been able to
use \translate to overlap a following piece of text in a line of markup.
 All the examples of \translate that I found in real scores apply it to
the entire markup (to shift the markup relative to its alignment point).
