It is not just being in shell.

Although I do agree that the initial clone is special, I would
rather make clone just a thin wrapper to fetch that also happens
to perform necessary initial setup.

Keeping fetched and updated refs in core and write a packed refs
out in one go in git-fetch--tool (and later, git-fetch all in C)
would be much simpler if we do not have to worry about existing
refs (aka "git clone" special case); I am not sure if packing
refs is desirable in general for incremental "git-fetch".
