Barlines disappear in one-line drum staff when reducing span - new when hiding/unhiding staves
Ubuntu 14.04, GIT commit: 2bf6819
1) new score, flute + snare drum
2) double click barline, drag down to extend barlines through staves
3) reverse the above operation (double click, drag up)
Result: drum staff is left with no barlines at all
Cause is Barline::endEdit() not taking the one-line status into consideration here:
This much at least is an easy fix.
