[PATCH] git svn branch fails with authenticaton failures

I have the following authentication failure while svn rebase and
svn dcommit works fine without authentication failures.

$ git svn branch v7_3
Copying https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx at r27519
to https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/v7_3...
Can't create session: Unable to connect to a repository at URL
'https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx': No more
credentials or we tried too many times.
Authentication failed at
C:\Program Files\Git\mingw64/libexec/git-core\git-svn line 1200.

I can workaround the issue to add auth configuration to
SVN::Client->new().
