copy ignore parameter

[Brendan Strejcek]

The official documentation for copy,

    http://www.cfengine.org/docs/cfengine-Reference.html#copy

says this about ignore:

    This works like the global ignore directive but here you may provide
    a private list of ignorable directories and files. Unlike include,
    exclude this affects the way cfengine parses directory trees.

What is mean by the word list? Comma-separated?

The docs for ignore,

    http://www.cfengine.org/docs/cfengine-Reference.html#ignore

do not shed any light on this either.

Do I want something like:

    ignore=RCS,CVS

or

    ignore=RCS
    ignore=CVS

or

    ignore=RCS:CVS

or something else? I suppose I could test them all until I find one
that works, but it seems like there are many possibilities that look
reasonable.
