Fixed.

Hm, I'm not too competent with handling lots of conflicts during an
interactive rebase: I'll try this out in a new branch and let you know
how it went.

I figured that adding some implies adding some others. Fixed.

Fixed. Excellent suggestion.

Here's the diff after your review. It took me quite a long time to get
the interactive rebase right.
Add skeleton dump editor
Add a no-op svn_editor and expose the function get_dump_editor; this
dump editor will later be filled in to write the dumpfile. Currently,
it is more useful to wrap it in the debug_editor to get a list of
editor operations printed to stderr.
