Editing git-svn metadata

Hello,

I couldn't find anything in the manpages for this, and I don't know  
where else to look for it.

As mentioned here: http://article.gmane.org/gmane.comp.version-control.git/116382 
  , an svn repository I'm working against has a weird layout on which  
git-svn chokes on. I'm working around that by using grafts to inform  
git about the history of the branches. It involves some manual work  
but it's fine.

Another problem I have (possibly linked) is that branches are only  
detected after the first commit to them - the commit that creates the  
branch is not recorded by git-svn at all. This forces me to do a  
'dummy' commit from svn in order to even see the branch in git-svn.

Given that I have all the information I need (branch name, parent id),  
is there any file I can manually edit to inform git-svn about my  
branches?

Alternatively, and more usefully to git in general, perhaps I can have  
a look at the git-svn code and add some diagnostics to see what's  
failing, and provide a patch? I looked for a developer guide but  
couldn't find one (only how to write tests).

Regards,
Orestis
