[PATCH] git svn: Don't create empty directories whose parents were deleted

[Greg Price <price@ksplice.com>]

Commit 6111b93 "git svn: attempt to create empty dirs on clone+rebase"
will create empty directories 'a/b' and 'a/c' if they were previously
created in SVN, even if their parent directory 'a' was deleted.

For example, unhandled.log may contain lines like this:

r32
  +empty_dir: packages/sipb-xen-remctl-auto/sipb-xen-remctl-auto/files/etc/remctl/sipb-xen-auto/acl
  +empty_dir: packages/sipb-xen-remctl-auto/sipb-xen-remctl-auto/files/etc/remctl/sipb-xen-auto/machine.d
  +empty_dir: packages/sipb-xen-remctl-auto/sipb-xen-remctl-auto/files/etc/remctl/sipb-xen-auto/moira-acl
[...]
r314
  -empty_dir: packages/sipb-xen-remctl-auto

This is a regression in v1.6.6-rc0, so it would be good to fix before v1.6.6.
