text at the end of a multimeasure rest

[Josiah Boothby]

I think I used to know how to do this but I can't find any evidence of it,
but I'd like to do something that looks roughly like the following, where
the text ("fine" or "D.C. al fine") are printed below the line:

|: /— 4 —/ :|: /— 4 —/ fine :|
|: /— 4 —/ :|: /— 4 —/ D.C. al fine :|

...while separating notes and time into separate variables. It seems like I
should be able to do this by simply setting text to right-align:

Time = {
  \repeat volta 2 { s1*4 }
  \repeat volta 2 { s1*4_\markup\right-align{ fine } }
  \repeat volta 2 { s1*4 }
  \repeat volta 2 { s1*4_\markup\right-align{ D.C. al fine } }
}

Notes = {
  R1*4
  R1*4
  R1*4
  R1*4
}

...but that's clearly not how it works, since the text ends up being
printed in the middle of the rest. Please remind me how to do this?

s1*3 s1_"fine"

ends up breaking the multimeasure rest, so is suboptimal.
