Indeed, "make externals" assumes that the other branches are in your
repository, in the remote called "origin".  For some reason your
local repository doesn't seem to be setup this way.

The "**/" glob is a zsh extension (supported also by Eshell, AFAIK),
whose meaning is clear enough.

This is because of the above error (the other matches are in exwm,
i.e. in the origin/externals/exwm branch).
