[pbs-devel] [PATCH proxmox-backup] fix #2996: client: allow optional match pattens for restore

[Gabriel Goller]

Gave this a quick spin and it worked quite good!

The only thing that didn't work was when I used '-' as a target, which
should print everything to stdout. When using it, the --matches
parameter is simply ignored and it dumps the whole archive on stdout.
E.g.:

    proxmox-backup-client restore --matches README.rst host/debian/2024-04-30T15:08:06Z test.pxar.didx -

Not sure if this is in the scope of this patch or not though.

If it isn't, you can consider:
