When auto-hinting, also try a "minimal" package set

Browse Source 
The minimal set is comprised of only the first level of (reverse)
dependencies, before any further iterations of packages are added to
the set.  In some cases, the result of the full iteration will contain
packages which cause problems when migrated but the minimal set,
although possibly a less optimal solution, may be able to migrate
successfully.

It is assumed that migrating the larger set of packages will be
preferred if possible, so minimal sets are tried later.
