Subject: RemoveEmptyStaves: Remove Harakiri engraver before adding it again.
X-Git-Tag: release/2.13.23-1~16
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=8142e0161b9c991808f1e9ddf77c4742479dc5d6;p=lilypond.git

RemoveEmptyStaves: Remove Harakiri engraver before adding it again.

If RemoveEmptyStaves is called twice (e.g. an include file with global
settings is included twice), two Hara_kiri_engravers would be added,
which leads to a warning.
This patch makes sure that no previous Hara_kiri_engraver is left
before adding a new one.
