manpages contain `<!-- Automatically generated by Pandoc -->`

I noticed this while verifying https://github.com/rubygems/gemstash/issues/396 locally, but it seems to also affect the released gemstash:

Seems to come from this template: https://github.com/jgm/pandoc-templates/blob/3430359b4c688dbedaa23d76575184191a12c4d9/default.man#L4-L7

I only looked briefly, but I haven't found an option to toggle it

Looks like `--variable "pandoc-version=" is enough to toggle it. docs on the variable, but unclear if there's any other side effects.

Um, we add that string ourselves! doc.rake has a line

::File.write to_file, "<!-- Automatically generated by Pandoc -->\n#{content}"
