rsync ssh remote paths are double-escaped (incorrect since rsync 3.2.4)

[stefanor]

Describe the bug

In 3.2.4 rsync changed the default way that arguments were passed to a remote ssh host, to no longer require double-escaping.

The bash-completion still double-escapes.

To reproduce

1. Create /tmp/foo bar on a remote machine (named remote)
2. Type rsync remote:/tmp/foo
3. Press tab.
4. Note that this completes to rsync remote:/tmp/foo\\\ bar, which is incorrect.

Expected behaviour

The remote path should only be escaped once, not twice (unless the --old-args argument is passed to rsync (>= 3.2.4)

Versions (please complete the following information)

• Operating system name/distribution and version: Debian testing
• bash version, echo "$BASH_VERSION": 5.2.2(1)-release
• bash-completion version, (IFS=.; echo "${BASH_COMPLETION_VERSINFO[*]}"): 2.11 (Debian: 1:2.11-6)

One year later the problem still there.
