Many pathnames in a fast-import stream need to be quoted. In
particular:
1. Pathnames at the end of an "M" or "D" line need quoting
if they contain a LF or start with double-quote.
2. Pathnames on a "C" or "R" line need quoting as above,
but also if they contain spaces.
For (1), we weren't quoting at all. For (2), we put
double-quotes around the paths to handle spaces, but ignored
the possibility that they would need further quoting.
This patch checks whether each pathname needs c-style
quoting, and uses it. This is slightly overkill for (1),
which doesn't actually need to quote many characters that
vanilla c-style quoting does. However, it shouldn't hurt, as
any implementation needs to be ready to handle quoted
strings anyway.
In addition to adding a test, we have to tweak a test which
blindly assumed that case (2) would always use
double-quotes, whether it needed to or not.

Breaks in a test assertion's && chain can potentially hide
failures from earlier commands in the chain.
Commands intended to fail should be marked with !, test_must_fail, or
test_might_fail. The examples in this patch do not require that.

This option adds symmetry with fast-import, enabling it to also work with
complete trees instead of just incremental changes. It works by issuing a
'deleteall' directive with each commit and then listing the full set of
files that make up that commit, rather than just showing the list of files
that have changed since the (first) parent commit. Note that this
functionality is automatically turned on when using --import-marks together
with path limiting in order to avoid dropping important but unchanged
files.
This functionality is desired when using hand-written filters along with
'fast-export | some-filter | fast-import' as it can be easier to write
<some-filter> in terms of complete trees than incremental changes.
We could avoid the need to add this option by simply always turning it on.
While the end result would be identical, it would slow things down slightly
by printing many more filenames per commit which goes somewhat against the
'fast' in 'fast-export'.

Since fast-export operates by listing file changes since the (first) parent
commit, when using --import-marks and path limiting and using a wider list
of paths than in previous runs, files from the new path(s) will silently be
omitted from the result unless or until a commit which explicitly changes
those files. The resulting repository in such cases is broken and makes no
sense.
This commit fixes this by having fast-export work with complete trees
instead of incremental changes (when both --import-marks and path limiting
are used). It works by issuing a 'deleteall' directive with each commit and
then listing the full set of files that make up that commit, rather than
just showing the list of files that have changed since the (first) parent
commit.

The fast-import stream format requires incremental changes which take place
immediately, meaning that for D->F conversions all files below the relevant
directory must be deleted before the resulting file of the same name is
created. Reversing the order can result in fast-import silently deleting
the file right after creating it, resulting in the file missing from the
resulting repository.
We correct this by first sorting the diff_queue_struct in depth-first
order.

Upon failure of any of these tests (or when a test that is marked as
expecting a failure is fixed), we will end up running later tests in
random places.
