Key signatures in hidden staves take up space

[Peter Crighton]

As you can see in the following code and the attached image, there is a possible bug when using \RemoveEmptyStaves with voices in different keys (such as in a score with transposing instruments): key signatures appearing only in hidden empty staves are still causing space in the shown staves.

\version "2.19.13"

<<

  \new Staff <<

    {

      c''1 \break

      c''2. \break

      c''1

    }

  >>

  \new Staff \with {

    \RemoveEmptyStaves

  } <<

    {

      \key d \major

      R1 \break

      \time 3/4 R2. \break

      \key c \major

      \time 4/4 R1

    }

  >>

>>

<<

  \new Staff <<

    {

      c''1 \break

      c''2. \break

      c''1

    }

  >>

  \new Staff <<

    {

      \key d \major

      R1 \break

      \time 3/4 R2. \break

      \key c \major

      \time 4/4 R1

    }

  >>

>>

I don’t think this is as it should be. How can I correct this? And should it be filed as a bug report, or is there some intention behind this appearance?
