=item git-debrebase new-upstream-v0 <new-version> [<upstream-details>...]
onto a new upstream version. In detail:
Firstly, checks that the proposed rebase seems to make sense:
-It is a problem unless the new upstream(s)
+It is a snag unless the new upstream(s)
are fast forward from the previous upstream(s)
as found in the current breakwater anchor.
-And, in the case of a multi-piece upstream,
+And, in the case of a multi-piece upstream
+(a multi-component upstream, in dpkg-source terminology),
if the pieces are not in the same order, with the same names.
If all seems well, unstitches and launders the branch.
If you git-rebase --abort,
the whole new upstream operation is aborted,
-but the laundering will still have been done.
+except for the laundering.
The <upstream-details> are, optionally, in order:

Default is C<upstream>.
-It is a problem if the upstream contains a debian/ directory;
+It is a snag if the upstream contains a debian/ directory;
if forced to proceed,
git-debrebase will disregard the upstream's debian/ and
take (only) the packaging from the current breakwater.
-=item <piece-name> <piece-upstream-commitish>
+=item <piece-name> <piece-upstream-commit-ish>
Specifies that this is a multi-piece upstream.
-(A multi-component upstream, in dpkg-source terminology.)
May be repeated.
When such a pair is specified,
and then use the result as the combined new upstream.
For each <piece-name>,
-the tree of the <piece-upstream-commitish>
+the tree of the <piece-upstream-commit-ish>
becomes the subdirectory <piece-name>
in the combined new upstream

git-debrebase does not concern itself with source packages
so neither helps with this, nor checks it.

This subcommand has -v0 in its name because we are not yet sure
that its command line syntax is optimal.
We may want to introduce an incompatible replacement syntax
under the name C<new-upstream>.

-(It is a problem for
