make --batch honor matching options
When --batch is used with matching options like --in, --metadata, etc, only
operate on the provided files when they match those options. Otherwise, a
blank line is output in the batch protocol.

Affected commands: find, add, whereis, drop, copy, move, get

In the case of find, the documentation for --batch already said it honored
the matching options. The docs for the rest didn't, but it makes sense to
have them honor them. While this is a behavior change, why specify the
matching options with --batch if you didn't want them to apply?

Note that the batch output for all of the affected commands could
already output a blank line in other cases, so batch users should
already be prepared to deal with it.

git-annex metadata didn't seem worth making support the matching options,
since all it does is output metadata or set metadata, the use cases for
using it in combination with the martching options seem small. Made it
refuse to run when they're combined, leaving open the possibility for later
support if a use case develops.

# NAME
git-annex copy - copy content of files to/from another repository
# SYNOPSIS
git annex copy `[path ...] [--from=remote|--to=remote]`
# DESCRIPTION
Copies the content of files from or to another remote.
# OPTIONS
* `--from=remote`
Copy the content of files from the specified
remote to the local repository.
Any files that are not available on the remote will be silently skipped.
* `--to=remote`
Copy the content of files from the local repository
to the specified remote.
* `--to=here`
Copy the content of files from all reachable remotes to the local
repository.
* `--jobs=N` `-JN`
Enables parallel transfers with up to the specified number of jobs
running at once. For example: `-J10`
* `--auto`
Rather than copying all files, only copy files that don't yet have
the desired number of copies, or that are preferred content of the
destination repository. See [[git-annex-preferred-content]](1)
* `--fast`
When copying content to a remote, avoid a round trip to check if the remote
already has content. This can be faster, but might skip copying content
to the remote in some cases.
* `--all` `-A`
Rather than specifying a filename or path to copy, this option can be
used to copy all available versions of all files.
This is the default behavior when running git-annex in a bare repository.
* `--branch=ref`
Operate on files in the specified branch or treeish.
* `--unused`
Operate on files found by last run of git-annex unused.
* `--failed`
Operate on files that have recently failed to be transferred.
* `--key=keyname`
Use this option to move a specified key.
* file matching options
The [[git-annex-matching-options]](1)
can be used to specify files to copy.
* `--batch`
Enables batch mode, in which lines containing names of files to copy
are read from stdin.
As each specified file is processed, the usual progress output is
displayed. If a file's content does not need to be copied, or it does not
match specified matching options, or it is not an annexed file,
a blank line is output in response instead.
Since the usual output while copying a file is verbose and not
machine-parseable, you may want to use --json in combination with
--batch.
* `--json`
Enable JSON output. This is intended to be parsed by programs that use
git-annex. Each line of output is a JSON object.
* `--json-progress`
Include progress objects in JSON output.
* `--json-error-messages`
Messages that would normally be output to standard error are included in
the json instead.
