I don't know what -m does.  Maybe try looking at the graph with gitk;
that might give some clues.

Then you'll get a conflict, and you'll have to fix it first before you
can dcommit.

Right.  I was just wondering whether you wanted the two branches'
contents to be *different* or identical.  I guess different.

For my own purposes, I try not to create a 1:1 mapping between local
branches and remote branches; this just ends up being confusing,
because I can have commits in my local branch that aren't in the
remote one, and vice versa.  So it's not very useful to create a local
branch *just* because I have a corresponding remote branch.

In your case, you might want to have just a single local branch for
your "public" stuff.  You would then merge changes from the two svn
remote branches into your local branch, and you'd also merge from your
local branch into your remote branches (using a disconnected HEAD and
svn dcommit).

Have fun,
