I think I got it.  My mistake was focusing all the time what I could
do with the git repository of "great" to facilitate two-way merges.

Instead I need to import great/trunk/dsp into a remote branch in my
_dsp_ git repository.  Since for git-svn, every Subversion directory
is as good to import as any other (there is no concept of a worktree
root in the repository) that should be all it takes.

I'll need to use the dsp repository when doing merge work, but apart
from that, I can work in the great repository r/w even while in the
dsp subdirectory.

If one could tell git in a remote section to
fetch/consider/synchronize/push just a subdirectory as the repo root,
then the same setup for bidirectional merges could be made to work
with projects like gitk.  Though I am fuzzy about the merge
information...  But that is a problem when pushing merges with private
branches, anyway, isn't it?
