Without this patch, users can make a clone partial by editing the repository configuration to convert the remote into a promisor, like: =C2=A0 git config core.repositoryFormatVersion 1 =C2=A0 git config extensions.partialClone origin =C2=A0 git fetch --unshallow --filter=3Dblob:none origin Since the hard part of making this work is already in place and such edits can be error-prone, teach Git to perform the required configuration change automatically instead. Note that this change does not modify the existing git behavior which recognizes setting extensions.partialClone without changing repositoryFormatVersion.
