copy/paste and "R" do not delete slurs or lines in target measures
1. Create two measures each containing at least one slur and a line.
2. Copy measure 1 and paste it over measure 2.
Result: Measure 2 now has all the slurs and lines combined from the old measure 2 and the pasted measure 1.
Expected result: Measure 2 should no longer contain anything from the old measure 2.
I am using MuseScore nightly ff2b92c on Kubuntu 14.04 64-bit.
Note: I did find this closed bug report: http://musescore.org/en/node/29446, but since it was dealing with a crash, I didn't re-open it, but created a new report instead.
