Colon is only confusing if one mistakes it for a comment.
Colon is not a comment, it's a command, and therefore included in xtrace
output.
Of course, the real problem is that colon's own exit status is always zero,
and that will prevent the exit status of the preceding command from
propagating out of a case/esac block or out of a function.
