Thanks, this sort-of worked.  Some of the reorganisation parts came
across cleanly, others appeared to be added rather than moved.  As far
as I can tell this is because one of the major parts of my
reorganisation was to lose the trunk/ branches/ tags/ part of the
repository, so I did something along the lines of:

svn mv -m "Repository reorganisation" svn://localhost/trunk/documents
svn://localhost/documents
svn mv -m "Repository reorganisation"
svn://localhost/trunk/configuration/vim
svn://localhost/applications/vim

Since none of these directories are working paths (the working paths
are applications/vim/vimfiles, documents/contacts,
documents/university/thesis etc), it seems to treat these as
independent add and deletes (although nothing appears in the log for
the delete, even with --log debug), so the history starts with the
repository reorganisation.

I guess I'll have to keep the subversion repository around in case
it's ever needed.  Not the end of the world: at least I seem to have
all of the projects accessible.  Having said that, if I can't browse
my repository without having to memorise the structure (see my other
thread), I can't see bazaar as being really usable yet, so I'll
probably just end up sticking with subversion... we shall see.

Thanks for the help anyway.
