Belated followup to #21981. (Looks like I started to add this functionality back in 2020 but left it unfinished. Tsk tsk.) docs/source/Commands.rst is unnecessary duplication. It _should_ be autogenerated, but I can't figure out how to cleanly add that to our Make process. This PR is an interim cross-check until we get that resolved: - everything in podman --help must have a matching entry in Commands.rst (top-level commands only) - check for dups and out-of-sequence in Commands.rst - also for anything in Commands.rst that is not in --help Fix existing mismatches in Commands.rst. Also, #21784 removed a format specifier that I was using in regression tests. Switch to using something else, to get test passing again. Given the fact the correct solution is autogenerating Commands.rst, I choose not to add new tests for the rst xref. Also, executive decision, remove volume.rst. It is not referenced from anywhere, it looks like a lonely orphan remnant from days of yore. Signed-off-by: Ed Santiago <santiago@redhat.com>
