Working my down the long tail of test failures due to the simple
store.
We're now down to 38 failures with the simple store.

Destination resolves to an empty set:
$ rebasewithdag -s B -d 'SRC - SRC' <<'EOS'
> C
> |
> B
> |
> A
> EOS
nothing to rebase - empty destination
[1]
Multiple destinations and --collapse are not compatible:
$ rebasewithdag -s C+E -d 'SRC^^' --collapse <<'EOS'
> C F
> | |
> B E
> | |
> A D
> EOS
abort: --collapse does not work with multiple destinations
[255]
Multiple destinations cannot be used with --base:
$ rebasewithdag -b B+E -d 'SRC^^' --collapse <<'EOS'
> B E
> | |
> A D
> EOS
abort: unknown revision 'SRC'!
[255]
Rebase to null should work:
$ rebasewithdag -r A+C+D -d 'null' <<'EOS'
> C D
> | |
> A B
> EOS

Destination resolves to multiple changesets:
$ rebasewithdag -s B -d 'ALLSRC+SRC' <<'EOS'

abort: rebase destination for f0a671a46792 is not unique

Destination is an ancestor of source:
