If the user specifes --out-format in rsync_opts return msg and stdout_lines in that format otherwise use the default for --itemize-changes, '%i %n%L'; the output for diff will always be in the default --itemize-changes format.
The use of '//' as a delimiter to split the format fields isn't perfect but it's the least-likely to clash with an actual filepath that I could think of.
Example :
cd "/home/a/ansible plays"
task:
- synchronize:
src: a
dest: b
Results in the following error being thrown
fatal: [remote-host]: FAILED! => {"changed": false, "cmd": "/usr/bin/rsync --delay-updates -F --compress --archive --rsh='/usr/bin/ssh -S none -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null' --rsync-path='sudo -u root rsync' --out-format='<<CHANGED>>%i %n%L' /home/a/ansible plays/deployments// remote-user@remote-host:/data/", "msg": "rsync: [sender] link_stat \"/home/a/ansible\" failed: No such file or directory (2)\nrsync: [sender] change_dir \"/home/a/ansible plays/plays/a/\" failed: No such file or directory (2)\nrsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1330) [sender=3.2.3]\n", "rc": 23}
The synchronize action plugin and module were a bit sloppy when it
came to the command-line parameter quoting and that caused failuer on
some systems (for example, on Fedora 34).
This commit makes sure any argumnts with potentially problematic
characters are quoted before being used.
