bug#11262: help text fro sorted? predicate is wrong/misleading.

[Alexei Matveev]

Hi, Guilers,

I seem to have almost convinced at least one another person that
the docstring of sorted? predicate is at least misleading:

guile> (sorted? '(0 0) <)
#t

guile> (help sorted?)
`sorted?' is a primitive procedure in the (guile) module.

 -- Scheme Procedure: sorted? items less
     Return `#t' iff ITEMS is a list or a vector such that for all 1 <=
     i <= m, the predicate LESS returns true when applied to all
     elements i - 1 and i

My suggestion for the docstring is below (feel free to improve my broken
english).
