`rsync` will not fully complete paths with spaces.

[Roy-Orbison]

Describe the bug

When the current completion is a file/dir, rsync will tab-complete up to and including an item with a space in its name but not below.

To reproduce

1. Make test dirs:

   mkdir -p foo\ qux/ba{r,z}

2. Complete from input like this:

   rsync foo

   or

   rsync 'foo

   It should get to this output:

   rsync foo\ qux/

   which works, or

   rsync 'foo qux'/

   which doesn't.
3. Continue completion for subdirectories (at least for the unquoted version).
4. Nothing further is output.

Replacing rsync with ls in the above examples will complete all as expected. I know they are not equivalent as rsync has to be more intelligent to do host names and remote items.

Expected behavior

It should complete items below the directory with spaces, e.g.:

rsync foo\ qux/ba
bar/ baz/

Versions (please complete the following information)

• Operating system name/distribution and version: Debian 13 & Ubuntu 26.04
• bash version, echo "$BASH_VERSION": 5.2.37(1)-release & 5.3.9(1)-release
• bash-completion version, (IFS=.; echo "${BASH_COMPLETION_VERSINFO[*]}"): 2.16.0

Additional context

I also tried with the latest version of the rsync.bash file from GitHub, same problem. I see no compgen -f in the trace.
