Subject: Fix #909.
X-Git-Tag: release/2.13.10-1~167
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=fc4d3f999aa4044bab4d26be3922a5441a6a6891;p=lilypond.git

Fix #909.

In the acknowledger for the bar-line-interface, a check to see if the
acknowledged grob contains the bar-line-interface is superfluous.

Instead, filter out SpanBar grobs (with a span-bar-interface check) in
the acknowledger so that SpanBars are not added to bars_ if more than
one Span_bar_engraver exists in a context.
