Primarily it's so that the person who pushed via dcommit and people who
sync via git-svn fetch get the same commit ID (assuming they are both
using the same authors map).

It might be possible to store the extra information needed to recreate
exactly the original git commit in SVN revision properties, but this
would need to be implemented once and basically not changed after that.

You can disable this behaviour, but you'll end up with duplicate commits.
