The above quote isn't really meaningfull at all, but one word remembered
me a bug (or misdocumentetation) in LilyPond :-)

I've problems using override-auto-beam-setting together with
revert-auto-beam-setting. I tried something like

| #(override-auto-beam-setting '(end * * * *) 3 4)
| <STUFF>
| #(revert-auto-beam-setting '(end * * * *))

but I get an error:

| lilypond (GNU LilyPond) 2.1.35
| [...]
| Interpreting music... [8][16][24][32][40][48][56][64][72]Backtrace:
| In unknown file:
|    ?: 0* [#<procedure #f (c)> #<Context Voice= () >]

|   Wrong number of arguments to #<procedure revert-property-setting
|   (context setting)>

I didn't find any single example of how to use revert-auto-beam-setting,
and the manual states that #(revert-auto-beam-setting `(be p q
n m)) is the correct way to use it. That seems to be wrong. Is
revert-auto-beam-setting broken?

Ciao,
	Kili

ps: sorry for not further investigating auto-beam.scm; I've still to
re-learn scheme.
