quite - that is garbage in the commit message;  and it seems may change if the 
SVN
repository is rehomed.

If there is another way to track these,  I'm all for it.  Using a reference 
seemed like
the simplest approach,  but one could create a parallel set of commits 
providing the
linkage,  or maybe git notes would work.

Actually,  looking through things,  it would be a reference,  but not a tag or 
branch.

Probably something like refs/svnid/yyyy/xx/rrr,  so that there are not too many 
entries
in a directory.  I was thinking yyy would be 'svn.gna.org' (since revisions are 
local
to a repository),  xx would be the top 16bits of the revision and rrr the 
complete revision.


Keeping the git-svn-id line in the git commit message is (I believe) one item 
that would
make bidir sync difficult,  as it is not a fixed line.  It would be missing in 
a native
git commit,  and then added when the commit synced back from svn - branching 
the git history,
and forcing rebases.
