Hi, in the course of the review of PR #404 we came to challenge the quite complex quoting rules allowed when you backup to/from a remote location.
Our question is if anybody is relying on those (too) complex quoting rules to make their backup work? Else it'll allow us to radically simplify the code. More details: if you backup to/from a remote site, the description is of the form `host::path` (e.g. `rdiff-backup /home myuser@myhost::/srv/backup/homebak`), and the current quoting allows to have the double colons (::) somewhere in the `host` or `path` part of the remote description. And the question is if anybody knows of a concrete use case for this possibility? For even more gory details, the man page states the quoting rules in the REMOTE OPERATION section. Thanks, Eric PS: and yes, double colons are a valid POSIX path part (`touch ::` works), but who really needs it? https://github.com/rdiff-backup/rdiff-backup/pull/404
