I think it is a bug.  It sounds like git-tar-tree is storing the wrong
set of permissions in the tar archive.  When I run "tar cf foo.tar
bar", and bar has permissions 0644, then tar inserts an entry into the
archive for "bar" with its permissions listed as 0644 (*not* 0666).
If "tar cf foo.tar bar" just ignored the permissions on bar and always
used a default of 0666 out of laziness, that would be a bug in "tar cf".
The same goes for git-tar-tree.  It seems to me that git-tar-tree ought
to behave the same as "tar cf".

In any case, regardless of whether this is by design or not, it is not
courteous to your users to distribute tar files where all the files have
permissions 0666.  That's not a user-friendly to do.
