And we could also have an attribute "repack" :
    == .gitattributes ==
    *.wmv    -repack
which would result in *.wmv files [enormous] not being packed.
Since add_object_entry() now gets the name and
can reject objects (e.g. currently on their current packing status),
a call to "no_pack" which mirrors your new "no_try_delta"
could be inserted there.  But such an attribute should be
ignored when --stdout is in effect -- it only affects on-disk
repacking, not packing for transfers, which is why it's named "repack".
