tl;dr:
- `git bundle create` without <git-rev-list-args> gives git rev-list
help, then dies.
Should point out missing <git-rev-list-args> instead.
- `git clone <bundle> <dir> gives "ERROR: Repository not found."
- `strace ... git clone <bundle> <dir>` (magically) appears to work but
cannot checkout files b/c of nonexistent ref.
- Heisenbug? Race condition?
- Zaphod Beeblebrox has left the building, sulking.
Full description:
When I try to clone from a bundle created from a local repository, `git
clone <bundle> <dir>` fails with: "ERROR: Repository not found. fatal:
Could not read from remote repository." unless I run it with strace.

error: rev-list died
$ # IMHO the error should refer to the usage of `git bundle` with a
proper basis, not `git rev-list`.
$ # Also nothing should die loudly because of a missing parameter.
