[LSR 2.20] broken: #889

[Thomas Morley]

Hi all,

Werner recently asked about lsr-upgrade, thus I had a first look.
http://lsr.di.unimi.it/LSR/Item?id=889
"Automatically coloring grobs to indicate when their direction has
been manually set" seems broken.
Boils down to:
\new Voice \with { \tweak color #red Slur } { a'( b') }
failing in 2.20.

Is there a direct replacement?
The snippet itself could be fixed by using \override rather then \tweak, imho.

Some others are broken as well, or complaining a lot ... step by step ...

Cheers,
  Harm
