borg import-tar / create / recreate: add --strip-components

Trying to use `borg import-tar`

[Docs](https://borgbackup.readthedocs.io/en/stable/usage/tar.html) say: _a `--tar-filter` program may be explicitly specified. It should read compressed data from **stdin** and output an uncompressed tar stream on **stdout**._

Can someone please show me how to do `tar -xzv --strip-components=1` as the filter program? I tried a few different ways but always just seems to hang..

`borg import-tar --tar-filter="tar -xzvf - --strip-components=1" /path/to/repo::archive-name /path/to/something.tar.gz`
`borg import-tar --tar-filter="tar -xzv --strip-components=1 -f -" /path/to/repo::archive-name /path/to/something.tar.gz`
etc..

Shouldn't `-f -` make tar read from stdin and output to stdout?
