The patch history feature was available in StGIT 0.1/0.2 releases
where you should have run a 'stg commit' before 'stg refresh'. The
commit was handling all the history changes, with separate commit
messages and refresh was updating the main commit with 2 parents. I
removed it in 0.3 after some people (I think it was Paul Jackson and
Daniel Barkalow) convinced me that this would make it yet another SCM
interface on top of GIT, which wasn't really my intention.

The main problem with having multiple parents for a commit object
corresponding to a patch is the upstream merging via 'git pull'. In
general you don't want a gatekeeper to pull the history of your patch
but the patch only.

'snapshot' is not yet used for anything and I'm not sure how it is
best to be implemented. I thought about simply saving the current HEAD
into some .git/refs/heads/<file>, without preserving any history for
the patch. A gitk on this file would show the patches as they were on
the time of the snapshot creation. A new snapshot would remove this.

It might be best for a per-patch history to have a separate file in
<branch>/<patch>/, maybe called freeze, which keeps this history
information. The top one should remain unchanged. Its hash could be
accessed with the 'stg id /freeze' command (implemented
yesterday). This file would only be updated via the 'freeze' command
and its parent would be the previous freeze value.

Would this be close to what you need?
