двунаправленная операция между репозиторием Subversion и Git (Bidirectional operation between a Subversion repository and Git)
MERGE TRACKING
While git svn can track copy history (including branches and
tags) for repositories adopting a standard layout, it cannot yet
represent merge history that happened inside git back upstream to
SVN users. Therefore it is advised that users keep history as
linear as possible inside Git to ease compatibility with SVN (see
the CAVEATS section below).
