The setting is called `lfs.remote.searchall`, the `remote` part of it being
an exact string, it is not to be expanded with the name of the remote.
Whenever name of the remote is to be used Git documentation uses `<remote>`
syntax.
Tested by triggering the original issue (clone the Github mirror, make update,
wait for a new LFS object appear in the upstream, make update again). Before
this change the LFS object will not be fetched, and based on the Git Curl's
log only the github origin was used to fetch LFS object, none other remotes
were tried.
Also confirmed by checking the Git-LFS code:
