Re: [RFC] Stgit - patch history / add extra parents

The parents which should be visible to the outside, will always be versions
of my development tree, which I have previously pushed out. My way of
working would become:
* make changes, all over the place, using stgit
* still make changes (none of these gets tracked, intermittent versions are
  lost)
* having a good day: changes looks good, I want to push this out:
  * push my tree out
  * stgit-free (which makes the pushed out commits, the new parents of my
    stgit patches)

When the tree status looks good, you could tag it and the whole stack
(the commits corresponding to the patches) would be available via this
tag.

As I said, I agree with the idea of freezing a patch and even having
multiple parents to a commit but this commit should not be visible via
HEAD. We could have another id for a patch, 'frozen', which stores the
last frozen state with the parents being the previous frozen
states. Its SHA1 value could be accessed via 'stg id <patch>/frozen'
(in the same way as /top and /bottom ids).
