Followup to #14906, in which a nonexistent option was found in a man page. The xref script was designed to catch that, but I was too lax in my parsing: the option was documented using wrong syntax, and the script didn't catch it. Solution: do not allow *any* unrecognized cruft in the option description lines. And fix all improperly-written entries to conform to the rule: **--option**=*value(s)* Two asterisks around option, which must have two dashes. One asterisk around value(s). This is going to cause headaches for some people adding new options, but I don't think I can fix that: there are many factors that make an unparseable line. Adding 'hint' code would make the script even more complex than it is. I have to assume that our contributors are smart enough to look at surrounding context and figure out the right way to specify options. Signed-off-by: Ed Santiago <santiago@redhat.com>

NAME
podman-import - Import a tarball and save it as a filesystem image
SYNOPSIS
podman import [options] path [reference]

DESCRIPTION
podman import imports a tarball (.tar, .tar.gz, .tgz, .bzip, .tar.xz, .txz)
and saves it as a filesystem image. Remote tarballs can be specified using a URL.
Various image instructions can be configured with the --change flag and
a commit message can be set using the --message flag.
reference, if present, is a tag to assign to the image.
podman import is used for importing from the archive generated by podman export, that includes the container's filesystem. To import the archive of image layers created by podman save, use podman load.
Note: :
