Work around a go-md2man bug, and add a check script to make sure
this doesn't hit us again.
Background: go-md2man can't deal with a left-hand column > 31 chars.
It produces man pages that look like:
| Something With >31 Character | |
| | ..description |
(should be all on one row). It also has trouble when the vertical
bars are misaligned: it completely removes the right-hand side.
There's almost certainly a better solution: fix go-md2man, or
use a different conversion tool, or maybe even pre/postprocess.
But this is a quick interim solution.
Sorry for the perl. This could be done in bash/sed/awk/grep,
but not with any sort of sane error messages.

Very belated successor to #14046.
I don't know why this is so important to me. Probably because we're
doing a halfhearted sloppy job of documenting, and new options get
added, and not documented, and that's just wrong.
I've given up on documenting internal structs. This iteration
has a $Format_Exceptions table defined at the top of the xref
script, enumerating a hardcoded defined set of podman commands
and fields that should remain undocumented.
This iteration also forgives completely-undocumented formats.
If podman-foo has a --format, but podman-foo.1.md does not
list *any* valid fields, the script warns but does not fail.
This at least is better than documenting a random mix of fields.
This version of the xref script is much slower: 10s vs 4. I
think we can live with that in a CI-only script.
