MetronomeMark markup

[Daniel Rosen]

I have a tempo marking that I want to split into two rows, as follows:

\version "2.16.1"
{
  \tempo \markup { \column { "Line 1" "Line 2" } } 4 = 100
  c'1
}

Is there a way for me to have the "4 = 100" part appear after "Line 2" without 
having to write out the quarter note, equals sign, etc. in markup?
