find: locate bits of ourselves symbolically
For the most part, Git does not care whether parts of the repository
are actually there or only there symbolically (i.e. via a symbolic
link). For historical reasons the refs namespace gets special
treatment with regard to symbolic links.
Make sure that Girocco also symbolically groks this kind of
arrangement. The hooks area gets special handling as any symbolic
links found there mean "hands off" during update-all-hooks time.
Some of the reports may need further fine tuning in this regard.
