git-svn bug/patch: Don't prompt for client cert password everytime.

Hi Eric,

I am using git-svn with a subversion repository using ssl client
certificates and I noted, that every time I do...

git-svn fetch

...for example, it prompts for my export passphrase, even though it is
given in ~/.subversion/servers.

I wrote a patch that fixes this (see attachment).

Btw, the patch I sent you before only works with an old version of git,
this one, attached to this email, works with current HEAD.

Regards
Sebastian Noack
