Hi,
Is anyone able to shed some light on "+r"?

GIT-LS-REMOTE(1) Git Manual GIT-LS-REMOTE(1)NAME
git-ls-remote - List references in a remote repository
SYNOPSIS
git ls-remote [--heads] [--tags] [-u <exec> | --upload-pack <exec>]
[--exit-code] <repository> [<refs>...]
DESCRIPTION
Displays references available in a remote repository along with the associated commit IDs.
OPTIONS -h, --heads, -t, --tags
Limit to only refs/heads and refs/tags, respectively. These options are not mutually exclusive; when given both, references stored in
refs/heads and refs/tags are displayed.
-u <exec>, --upload-pack=<exec>
Specify the full path of git-upload-pack on the remote host. This allows listing references from repositories accessed via SSH and
where the SSH daemon does not use the PATH configured by the user.
--exit-code
Exit with status "2" when no matching refs are found in the remote repository. Usually the command exits with status "0" to indicate it
successfully talked with the remote repository, whether it found any matching refs.
--get-url
Expand the URL of the given remote repository taking into account any "url.<base>.insteadOf" config setting (See git-config(1)) and
exit without talking to the remote.
<repository>
The "remote" repository to query. This parameter can be either a URL or the name of a remote (see the GIT URLS and REMOTES sections of
git-fetch(1)).
<refs>...
When unspecified, all references, after filtering done with --heads and --tags, are shown. When <refs>... are specified, only
references matching the given patterns are displayed.
EXAMPLES
$ git ls-remote --tags ./.
