Comment #16 on issue 4191 by address@hidden: Patch: Add an "\or"  
markup command
https://code.google.com/p/lilypond/issues/detail?id=4191

\first-visible is the best suggestion so far.  I've put it in the "other"  
category of markup commands; is that the best place?

What do you think about separating the two aspects of this problem, for  
example,

    \choose #1 \choose-visible {...}

I can see other uses for those commands, but they're not as pretty together  
as \first-visible.

\choose might be used to choose a slice of lines from a list, for example  
in formatting a verse with some lines that are very short in comparison to  
others,

    \column {
        \choose #1 #stanzaLines
        \choose #2 #stanzaLines
        \join-line " / " \choose #'(3 . 4) #stanzaLines
        \choose #5 #stanzaLines
    }

\choose-visible might be useful before joining markups with a separator.
