Added --no-check-gitignore option for finer grained control than using --force.
add, addurl, importfeed, import: Added --no-check-gitignore option
for finer grained control than using --force.

(--force is used for too many different things, and at least one
of these also uses it for something else. I would like to reduce
--force's footprint until it only forces drops or a few other data
losses. For now, --force still disables checking ignores too.)

addunused: Don't check .gitignores when adding files. This is a behavior
change, but I justify it by analogy with git add of a gitignored file
adding it, asking to add all unused files back should add them all back,
not skip some. The old behavior was surprising.

In Command.Lock and Command.ReKey, CheckGitIgnore False does not change
behavior, it only makes explicit what is done. Since these commands are run
on annexed files, the file is already checked into git, so git add won't
check ignores.

# NAME
git-annex addurl - add urls to annex
# SYNOPSIS
git annex addurl `[url ...]`
# DESCRIPTION
Downloads each url to its own file, which is added to the annex.
When `youtube-dl` is installed, it can be used to check for a video
embedded in a web page at the url, and that is added to the annex instead.
(However, this is disabled by default as it can be a security risk.
See the documentation of annex.security.allowed-ip-addresses
in [[git-annex]](1) for details.)
Special remotes can add other special handling of particular urls. For
example, the bittorrent special remotes makes urls to torrent files
(including magnet links) download the content of the torrent,
using `aria2c`.
Normally the filename is based on the full url, so will look like
"www.example.com_dir_subdir_bigfile". In some cases, addurl is able to
come up with a better filename based on other information. Options can also
be used to get better filenames.
# OPTIONS
* `--fast`
Avoid immediately downloading the url. The url is still checked
(via HEAD) to verify that it exists, and to get its size if possible.
* `--relaxed`
Don't immediately download the url, and avoid storing the size of the
url's content. This makes git-annex accept whatever content is there
at a future point.
This is the fastest option, but it still has to access the network
to check if the url contains embedded media. When adding large numbers
of urls, using `--relaxed --raw` is much faster.
* `--raw`
Prevent special handling of urls by youtube-dl, bittorrent, and other
special remotes. This will for example, make addurl
download the .torrent file and not the contents it points to.
* `--file=name`
Use with a filename that does not yet exist to add a new file
with the specified name and the content downloaded from the url.
If the file already exists, addurl will record that it can be downloaded
from the specified url(s).
* `--preserve-filename`
When the web server (or torrent, etc) provides a filename, use it as-is,
avoiding sanitizing unusual characters, or truncating it to length, or any
other modifications.
git-annex will still check the filename for safety, and if the filename
has a security problem such as path traversal or an escape sequence,
it will refuse to add it.
* `--pathdepth=N`
Rather than basing the filename on the whole url, this causes a path to
be constructed, starting at the specified depth within the path of the
url.
For example, adding the url http://www.example.com/dir/subdir/bigfile
with `--pathdepth=1` will use "dir/subdir/bigfile",
while `--pathdepth=3` will use "bigfile".
It can also be negative; `--pathdepth=-2` will use the last
two parts of the url.
* `--prefix=foo` `--suffix=bar`
Use to adjust the filenames that are created by addurl. For example,
`--suffix=.mp3` can be used to add an extension to the file.
* `--no-check-gitignore`
By default, gitignores are honored and it will refuse to download an
url to a file that would be ignored. This makes such files be added
despite any ignores.
* `--jobs=N` `-JN`
Enables parallel downloads when multiple urls are being added.
For example: `-J4`
Setting this to "cpus" will run one job per CPU core.
* `--batch`
Enables batch mode, in which lines containing urls to add are read from
stdin.
* `-z`
Makes the `--batch` input be delimited by nulls instead of the usual
newlines.
* `--with-files`
When batch mode is enabled, makes it parse lines of the form: "$url $file"
That adds the specified url to the specified file, downloading its
content if the file does not yet exist; the same as
`git annex addurl $url --file $file`
* `--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.
# CAVEATS
If annex.largefiles is configured, and does not match a file, `git annex
addurl` will add the non-large file directly to the git repository,
instead of to the annex. However, this is not done when --fast or --relaxed
is used.
