We just changed the standard doclet so that when it copies
doc-files, it also copies all of its subdirectories
(previously it did not copy any of its subdirectories).
As stated below, this winds up copying the SCCS directory,
which breaks the bringover.

We could either hard-code it to not copy any directory named "SCCS",
or provide an option to specify the name of the directory
it should ignore.

This is a bit nasty.

- If we hard-code directory names, we would have to include
  all possible directory names used for source code control
  under all operating systems.

- If we provide an option to exclude SCCS, that means that
  all scripts for javadoc that operate on code under source
  control are effectively broken, and all need to be changed.
  It also means that this option would always be required by
  any code under source code control, even if you don't use
  doc-files (which includes virtually all of the simple cases,
  and most of the rest)

I propose we return to the original default behavior
of not doing a deep copy of doc-files. Jamie, unless you
have other alternatives, we should make this change ASAP.

Then add an option for deep copy, that allows the exclusion
of certain directory names. I suggest an option something
like "copydocfiles" that takes "shallow" or "deep" as its
argument, where "shallow" is the default.

  -copydocfiles shallow|deep

As far as excluding the SCCS directory, it seems we should
have a general mechanism for skipping SCCS directories,
possibly using the existing -exclude option.
If a general mechanism isn't needed, we could create a special
case such as:

  -excludedocfilesdir SCCS
