That's interesting. My superficial understanding of git (also) is that the user stores the entire history of a project locally (with the advantage that checking stuff in and out is very fast). That means that apparently the PLplot history is stored very efficiently since the git size is only a little larger than the svn size. Also, I didn't spend enough time learning git to figure out what advantage there is when updating the master with a local repo--there still must be issues with conflicts. And is there any mechanism to lock a file while it is being edited, since it is checked out from the local repo and the master has no clue of the file's status. I recall we had a discussion of this recently w.r.t. svn where most agreed that conflicts like this are a rare event but there is indeed a locking mechanism of some sort if one chooses to use it.
