RE: doc string for `yank' should mention "paste"

[Drew Adams]

        Similarly, some basic operations on the region should
        mention the term "selection" as being synonymous with
        "region". `M-x apropos-documentation
        region', then search for `selection' finds nothing.

    How about this?

    + Setting the mark also creates a \"region\", which is the Emacs
    + equivalent of what is called a \"selection\" in some other editors.

Perfect. Thanks.

(A detail: The region exists always. Setting the mark just redefines its
boundary; it doesn't really create "a" region. This is one difference in
terminology, which perhaps needs to be pointed out at some point, so people
will understand language like "the" region. Selecting text creates a
selection, and it redefines the region to be that selection (the selected
text).)
