Mumi Feature Request: Easier way to apply patches from web interface

[jgart]

Hi Guixers, 

This is a feature request for mumi.

What do you think if mumi had a feature that gives the user a generated command 
like this one (the following url is probably not correct) and shows it in the 
web interface for each patch series?

curl -s https://issues.guix.gnu.org/issue/61036/raw/1 | git am -3

The new user can then just copy paste the above command to apply the patch and 
review it. 

sr.ht's mailing list service implements the feature:

https://lists.sr.ht/~whereiseveryone/bangs/patches/38520

See on the right in the html where it says "How do I use this?":

https://lists.sr.ht/~whereiseveryone/toys/patches/38089

The code for that implementation is here:

https://git.sr.ht/~sircmpwn/lists.sr.ht/tree/master/item/listssrht/templates/patchset.html#L174

It looks like they are using their graphql API to get that information for the 
jinja template:
