argp should probably just not print name fields that are empty, e.g., replace

        if (opt->name && ovisible (opt))

with

        if (opt->name && *opt->name && ovisible (opt))

or so.

[Normally I suppose the issue doesn't come up because argp automatically
fills the doc-string, so it's usually not necessary to have "continuation"
entries like that.]
