Let's clarify. We can mean two possible things when we say 'a series of
patches':
1. "patch versions": a series of successively better patches, all
attempting the same logical thing, all from the same base, and only one
of which is applied at any time;
2. a series of patches, each providing a different logical change,
where each patch is based on the result of applying the previous one.
("quilt" is a tool for managing path series of this kind. My 'option 3'
(local repository) design for checkpointing could also be used in this
way, in a primitive way, but would not support revising earlier patches
in the series which is a key strength of what "quilt" can do.)
I am talking about definition 1 ("patch versions").
I propose patches in a series of patch versions be named "featureA-1",
"featureA-2", ... (This is what I do already, manually, in my own work.)
I propose that we should not attempt to provide any special support for
definition 2 within this "shelving" feature; users can manage that
themselves by simply remembering which feature names depend on which
other ones, or by including some other numbering system within the names.

Good thought.
