Gawk and mairix are not parts of Emacs, they are separately-maintained
programs.  So their manuals cannot be reached via the common base of
the Emacs manuals, and therefore they should not be in that list,
indeed.

>   Info-urls since they response with HTTP status "not found".
> - Check if there are more Emacs-included manuals, perhaps ones that are
>   not "one page per node".
> - Improve and revisit NEWS, CHANGELOG and commit message.
> - Adhere to fill-column.
> - FSF copyright assignment.
> 
> Also I have some questions:
> 
> - What do you think about the naming of the Info-urls variable?
> - Is the position of the definition of Info-urls fine?

I will review the patch in a couple of days, so if you have more
changes, please feel free to post updated patches.  There's no rush.
