upload-pack.c: fix filter spec quoting bug
Fix a bug in upload-pack.c that occurs when you combine partial
clone and uploadpack.packObjectsHook. You can reproduce it as
follows:
git clone -u 'git -c uploadpack.allowfilter '\
'-c uploadpack.packobjectshook=env '\
'upload-pack' --filter=blob:none --no-local \
src.git dst.git
Be careful with the line endings because this has a long quoted
string as the -u argument.
The error I get when I run this is:
Cloning into '/tmp/broken'...
remote: fatal: invalid filter-spec ''blob:none''
error: git upload-pack: git-pack-objects died with error.
fatal: git upload-pack: aborting due to possible repository corruption on the remote side.
remote: aborting due to possible repository corruption on the remote side.
fatal: early EOF
fatal: index-pack failed
The problem is caused by unneeded quoting.
This bug was already present in 10ac85c785 (upload-pack: add object
filtering for partial clone, 2017-12-08) when the server side filter
support was introduced. In fact, in 10ac85c785 this was broken
regardless of uploadpack.packObjectsHook. Then in 0b6069fe0a
(fetch-pack: test support excluding large blobs, 2017-12-08) the
quoting was removed but only behind a conditional that depends on
whether uploadpack.packObjectsHook is set.
Because uploadpack.packObjectsHook is apparently rarely used, nobody
noticed the problematic quoting could still happen.
Remove the conditional quoting and add a test for partial clone in
t5544-pack-objects-hook.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
