I believe this last line is not valid Texinfo.  Since the description is
already a big verbose, I’d suggest removing it.

Please use three dots and rendering will replace it with HORIZONTAL
ELLIPSIS if the current locale encoding supports it (well, it doesn’t do
it yet, but someday.)

Hi Pierre,

Sorry for the delay getting back to you!

I had a cursory look and it all LGTM, modulo minor issues I reported
(please make sure to run ‘guix lint’ on all of them and fix any issues
it reports—I’ve seen a couple of minor things that it should notice.)

I figured the easiest way to apply it would be to give you commit
access.  :-)

Could you create an account on Savannah, add the OpenPGP public key that
you’ll use to sign commits there, and reply with a message signed with
that public key?

Once you’re done, please read the commit access rules in the ‘HACKING’
file.

Thank you!

Ludo’.

Hi Ludo!

Thanks for this fantastic show of trust, I'm very grateful!
You've made my day! :)

I already have an account on Savannah: "ambrevar".
This e-mail should be signed with the same key.

I'll study this HACKING file carefully.

Let me know if there is anything else.

Cheers!
Pierre

I’ve added you to the Savannah group, so I think we’re all set!

Please let us know if you have any questions or if you’re in doubt with
Git, or with what goes to which branch, etc.

Welcome aboard!  :-)
