LilyPond overrides with pre-2.18 syntax

[ksnortum]

As per David Kastrup in the LilyPond users' forum:

Calling

git grep "\\\\override[^=]*#'[a-z]"

in the current Frescobaldi source tree delivers way too many hits.

Search for all "bad" overrides in the code base and bring them up to post-2.18 syntax, for instance:

\override Tie #'thickness = #2

becomes

\override Tie.thickness = #2

And a way should be found to fix any overrides that span line breaks.

Should be fixed. Please reopen if you find a missing spot.

There's a "clever" one hidden in two lines in clef_treble_8.ly, lines 7 and 8. (Sorry, I don't know how to re-open the issue.)

[jeanas]

Ah yes, fixed in b6bc6e8.

(Sorry, I don't know how to re-open the issue.)

Ok, then I guess people without triage access to the repository can't reopen issues.
