The cruft pack feature has two primary test scripts which exercise
various parts of it, which are:
- t5329-pack-objects-cruft.sh
- t7704-repack-cruft.sh
The former is designed to test low-level pack generation mechanics at
the 'git pack-objects --cruft'-level, which is plumbing. The latter, on
the other hand, is designed to test the user-facing behavior through
'git repack --cruft', which is porcelain (under the "ancillary
manipulators" sub-section).
At some point a handful of tests which should have been added to the
latter script were instead written to the former. This isn't a huge
deal, but rectifying it is straightforward. Move a handful of
'repack'-related tests out of t5329 and into their rightful home in
t7704.
