[Lilypond-auto] [LilyIssues-auto] [testlilyissues:issues] #5097 Fix programming errors associated with texted HorizontalBracket grobs

[Auto mailings of changes to Lily Issues]

Well, of course tweaking the text of the bracket grob will still cause the error/warning. But it would also stop appearing to work in spite of the warning. And tweaking thickness will not cause HorizontalBracketText to complain. So that's half of the warnings disappearing, and the other half of the warnings actually pointing out something going wrong.

The proposal was just supposed to make stuff behave more predictably, not more conveniently. Whether that's good enough is another question.

It would also be imaginable that HorizontalBracket gets the text interface and will have its text settings used for initializing those of HorizontalBracketText (unless overridden). That's a lot more handwavy but will probably generally work as expected.

HorizontalBracket and HorizontalBracketText are both created from the same event. Thus, a tweak of a property not possessed by both grobs (such as 'text or 'thickness) will result in a programming error, unless the tweak is directed at the correct grob.

Example:

\layout {
  \context {
    \Voice
    \consists "Horizontal_bracket_engraver"
  }
}

{
  c'' -\tweak text "foo" \startGroup d'' e'' f''\stopGroup
}
