I was working on that when I hit this. Besides the one you mentioned,
the xterm-specific `DECSED 3` is missing, for example. I'm sure there
was something with one of the string controls too ...

Source means "preferred format for modification", not "in a tarball
somewhere". By your definititon, all of Windows is open-source.

By using environment variables and extra pipe commands. But in any
case, a version *without* stripping all that formatting info, viewable
in the terminal, would be nice.

That's a matter of opinion. Using the letter `o` for bullets is
particular ugly to me.

You mean the format that is identical to the format you produce, other
than the (admittedly better) filenames for the included `.png`s?
