Subject: Fix #691: setting \tempo without duration shouldn't  print a duration
X-Git-Tag: release/2.11.62-1~25^2
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=7e2d3e7e87fa65f5b67ffa64a4749c952debf048;p=lilypond.git

Fix #691: setting \tempo without duration shouldn't  print a duration

We can turn off the printing of (dur=count) by simply unsetting the count and duration properties (they are unset in the beginning, so I don't think this will break anything, but then, I'm not totally sure...)
Also added a show regtest for this case.
