Antoine Beaupré 21ec5872f4 expand manpages cross-references significantly
i found that most man pages only had references to the main git-annex
manpage, which i stillfind pretty huge and hard to navigate through.

i tried to sift through all the man pages and add cross-references
between relevant pages. my general rule of thumb is that links should
be both ways unless one of the pages is a more general page that would
become ridiculously huge if all backlinks would be added
(git-annex-preferred-content comes to mind).

i have also make the links one per line as this is how it was done in
the metadata pages so far.

i did everything but the plumbing, utility and test commands, although
some of those are linked from the other commands so cross-links were
added there as well.

# NAME
git-annex metadata - sets or gets metadata of a file
# SYNOPSIS
git annex metadata `[path ...]`
# DESCRIPTION
The content of an annexed file can have any number of metadata fields
attached to it to describe it. Each metadata field can in turn
have any number of values.
This command can be used to set metadata, or show the currently set
metadata.
When run without any -s or -t parameters, displays the current metadata.
# OPTIONS
* `-g field`
Get the value(s) of a single field.
The values will be output one per line, with no other output, so
this is suitable for use in a script.
* `-s field=value`
Set a field's value, removing any old values.
* `-s field+=value`
Add an additional value, preserving any old values.
* `-s field-=value`
Remove a value.
* `-s field?=value`
Set a value, but only if the field does not already have a value set.
* `-t tag`
Set a tag. Note that a tag is just a value of the "tag" field.
* `-u tag`
Unset a tag.
* `--force`
By default, `git annex metadata` refuses to recursively set metadata
throughout the files in a directory. This option enables such recursive
setting.
* file matching options
The [[git-annex-matching-options]](1)
can be used to specify files to act on.
* `--json`
Enable JSON output. This is intended to be parsed by programs that use
git-annex. Each line of output is a JSON object.
* `--all`
Specify instead of a file to get/set metadata on all known keys.
* `--unused`
Specify instead of a file to get/set metadata on
files found by last run of git-annex unused.
* `--key=keyname`
Specify instead of a file to get/set metadata of the specified key.
# EXAMPLES
To set some tags on a file and also its author:
git annex metadata annexscreencast.ogv -t video -t screencast -s author+=Alice
