Some pipes in tests lose the exit code of git processes, which can mask
unexpected behavior like crashes. Split these pipes up so that git
commands are only at the end of pipes rather than the beginning or
middle.
The violations fixed in this patch were found in the process of fixing
pipe placement in a prior patch.

Fix various places where the ordering was obviously wrong, meaning it
was easy to find with grep.

Instead of using a line-continuation and pipe on the second line, take
advantage of the shell's implicit line continuation after a pipe
character. So for example, instead of
some long line \
| next line
use
some long line |
next line
And add a blank line before and after the pipe where it aids readability
(it usually does).
This better matches the coding style documented in
Documentation/CodingGuidelines and used in shell scripts elsewhere in
the tree.

A filter line in a request to upload-pack filters out objects regardless
of whether they are directly referenced by a "want" line or not. This
means that cloning with "--filter=blob:none" (or another filter that
excludes blobs) from a repository with at least one ref pointing to a
blob (for example, the Git repository itself) results in output like the
following:
error: missing object referenced by 'refs/tags/junio-gpg-pub'
and if that particular blob is not referenced by a fetched tree, the
resulting clone fails fsck because there is no object from the remote to
vouch that the missing object is a promisor object.
Update both the protocol and the upload-pack implementation to include
all explicitly specified "want" objects in the packfile regardless of
the filter specification.

Teach pack-objects to use the filtering provided by the
traverse_commit_list_filtered() interface to omit unwanted
objects from the resulting packfile.
Filtering requires the use of the "--stdout" option.
Add t5317 test.
In the future, we will introduce a "partial clone" mechanism
wherein an object in a repo, obtained from a remote, may
reference a missing object that can be dynamically fetched from
that remote once needed. This "partial clone" mechanism will
have a way, sometimes slow, of determining if a missing link
is one of the links expected to be produced by this mechanism.
This patch introduces handling of missing objects to help
debugging and development of the "partial clone" mechanism,
and once the mechanism is implemented, for a power user to
perform operations that are missing-object aware without
incurring the cost of checking if a missing link is expected.
