Bad refspec messes up bundle.

Yesterday I created a git bundle as best as I can remember like this

git bundle save chunk chunk.bundle --all master

Note the 'master' I added accidentally at the end - this was a user error but still the bundle was created.

When I tried to clone this, I get

~\local\src> git clone 'G:\My Drive\chunk.bundle' fs2-columns Cloning into 'fs2-columns'... Receiving objects: 100% (31/31), done. Resolving deltas: 100% (5/5), done. fatal: multiple updates for ref 'refs/remotes/origin/master' not allowed. ~\local\src> git bundle verify chunk.bundle The bundle contains these 3 refs: 3c804437a5f8537db1bfb5d09b7bff4f9950605e refs/heads/master 3c804437a5f8537db1bfb5d09b7bff4f9950605e HEAD 3c804437a5f8537db1bfb5d09b7bff4f9950605e refs/heads/master The bundle records a complete history. chunk.bundle is okay

After trying a couple of things, I finally managed to clone it using

~\local\src> git clone -b master --single-branch .\chunk.bundle fs2-columns

i.e. the '--single-branch' option saved me.

Is this a bug? Should bundle allow providing multiple refspecs when `--all` is provided? I admit this was clearly a case of 'caveat emptor', but shouldn't this be disallowed (i.e. is there any situation when this is useful?)

Thanks!

Luciano
