bug#6528: 24.0.50; `read-buffer' doc string

[Drew Adams]

The doc string says:
 
 Optional third arg REQUIRE-MATCH determines whether non-existing
 buffer names are allowed.  It has the same meaning as the
 REQUIRE-MATCH argument of `confirm-after-completion'.
 
The last sentence is incorrect (meaningless): `confirm-after-completion'
is not a function, and it has no arguments.
