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 whereis - lists repositories that have file content
# SYNOPSIS
git annex whereis `[path ...]`
# DESCRIPTION
Displays information about where the contents of files are located.
For example:
# git annex whereis
whereis my_cool_big_file (1 copy)
0c443de8-e644-11df-acbf-f7cd7ca6210d -- laptop
whereis other_file (3 copies)
0c443de8-e644-11df-acbf-f7cd7ca6210d -- laptop
62b39bbe-4149-11e0-af01-bb89245a1e61 -- usb drive [here]
7570b02e-15e9-11e0-adf0-9f3f94cb2eaa -- backup drive
# OPTIONS
* file matching options
The [[git-annex-matching-options]](1)
can be used to specify files to act on.
* `--key=keyname`
Show where a particular git-annex key is located.
* `--all` `-A`
Show whereis information for all known keys.
* `--branch=ref`
Show whereis information for files in the specified branch or treeish.
* `--unused`
Show whereis information for files found by last run of git-annex unused.
* `--batch`
Enables batch mode, in which a file is read in a line from stdin,
its information displayed, and repeat.
Note that if the file is not an annexed file, or does not match
specified file matching options, an empty line will be
output instead.
* `--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-error-messages`
Messages that would normally be output to standard error are included in
the json instead.
