clone: --dissociate option to mark that reference is only temporaryjc/clone-borrow
While use of the --reference option to borrow objects from an
existing local repository of the same project is an effective way to
reduce traffic when cloning a project over the network, it makes the
resulting "borrowing" repository dependent on the "borrowed"
repository. After running
git clone --reference=P $URL Q
the resulting repository Q will be broken if the borrowed repository
P disappears.
The way to allow the borrowed repository to be removed is to repack
the borrowing repository (i.e. run "git repack -a -d" in Q); while
power users may know it very well, it is not easily discoverable.
Teach a new "--dissociate" option to "git clone" to run this
repacking for the user.
