Re: [PATCH v2] upload-pack: allow shallow fetching from a read-only repository

If only there is a way to pass this info without a temporary

Wait it does not look that ugly. We can feed "--shallow <SHA1>" lines
before sending want/have/edge objects. Something like this seems to
work (just ran a few shallow-related tests, not the whole test suite)

Sounds like it is a much better approach to the issue.
