To use the backport commit (using caja as an example)

$ git clone git@github.com:mate-desktop/caja.git
$ cd caja
$ git remote add nautilus git@gitlab.gnome.org:GNOME/nautilus.git
$ git fetch nautilus

Now the upstream project is set up as a remote in the downstream. Then:

$ git backport <commit hash from nautilus>

This will open two instances of meld: one with the change within nautilus, as reference, and one instance from nautilus to caja. Think of it as a poor-man's three-way diff. Once the right lines are moved from nautilus to caja, close meld and this will show up in terminal:

$ ...
foo bar commit title

commit description blah blah

upstream commit:
https://gitlab.gnome.org/GNOME/nautilus/commit/
https://github.com/mate-desktop/caja/commit/
2ac89eff

So you copy that thing and run git commit -a and paste that, removing the caja line to append the hash to the nautilus URL, ending with the following commit message:

foo bar commit title

commit description blah blah

upstream commit:
https://gitlab.gnome.org/GNOME/nautilus/commit/2ac89eff
