[PATCH v2 0/3] Supporting partial clones in protocol v2

Thanks, Brandon. I went ahead and used repo_config_get_bool(), and
indeed it works.

Removing the call to git_config() from there exposed another issue in
that configs were not read if upload-pack was used with protocol v2, so
I inserted a patch in the middle addressing that. While writing that
patch, I noticed that uploadpack.packobjectshook couldn't take filenames
with spaces, which I think is due to prepare_shell_cmd() in
run-command.c not quoting properly. Adding single quotes around "%s"
worked, but made other tests fail. Instead of continuing down that
rabbit hole, I just made the uploadpack.packobjectshook not have any
spaces, just like in t5544.
