bug in docs?

[Andrzej Kopeć]

[Gentoo Linux, Lilypond 2.6.1]

There is in documentation in chapter 8.6.2 :

   #(revert-auto-beam-setting '(be p q n m ) [context ])

where it should be:

   #(revert-auto-beam-setting '(be p q n m ) a b [context ])

to work properly.
Without definig a/b duration lily throws out an error ("wrong number of
arguments").
I don't know if these arguments are redundant in this function.
I haven't seen any effect when using them. (but that isn't the point)
