Thanks; I spent a while thinking about that part of the workflow.  I
save the current series as a symbolic ref SHEAD, and everything operates
on SHEAD.  (I should probably add support for running things like "git
series log" or "git series format" on a different series, because right
now "until told otherwise" doesn't include a way to tell it otherwise.)

One fun detail that took a couple of iterations to get right: I keep
separate "staged" and "working" versions per-series, so even with
outstanding changes to the cover letter, base, or series, you can always
detach or checkout another series without losing anything.  If you
switch back, all your staged and unstaged changes will remain staged and
unstaged where you left them.  That solves the "checkout a different
series with modifications to the current series" case.

By all means.  For a review tool like git-candidate, it seems like you'd
want even more contextual information, to make it easier to specify
things like "comment on file F line L".  For instance, what if you
spawned the diff to review in an editor, with plenty of extra context
and a file extension that'll cause most editors to recognize it as a
patch (and specifically a git-candidate patch to allow specialized
editor modes), and told people to add their comments after the line they
applied to?  When the editor exits successfully, you can scan the file,
detect the added lines, and save those as comments.  You could figure
out the appropriate line by looking for the diff hunk headers and
counting line numbers.

If you use a format-patch diff that includes the headers and commit
message, you could also support commenting on those in the same way.
Does the notedb format support commenting on those?

Thanks!
