purpose of -r flag for git-svn fetch

purpose of -r flag for git-svn fetch

[Bradley Wagner]

I've tried doing git-svn fetch in batches because it takes too long to
do it all at once.

    git svn -r1:5000 fetch
    git svn -r5000:10000 fetch
    git svn -r10000:15000 fetch

Strangely, after this is done if I look in the history with "git log",
I only see commits on master branch up through the 5000th revision of
the SVN repository. Someone told me to then call git-svn rebase to fix
it. What does "-r" actually do when invoked on consecutive calls to
"git-svn fetch" and why does git-svn rebase appear to fix it?

I posted this question to Stackoverflow before realizing that this
list is a better audience for it:

Thanks!

The keyword here is "fetch". "fetch" only retrieves data into the
remote-tracking branch (often called refs/remotes/git-svn), without
updating your local branches. "git svn rebase", on the other hand,
rebases your currently-checked-out branch to be based on the git-svn
remote ref. (note that "git svn rebase" does a "git svn fetch"
behind-the-scenes first, and is actually just "git svn fetch" followed
by a normal "git rebase")

The concepts are the same as if you were using the regular git commands
"fetch" and "rebase", so the man pages for those may offer some insight.

Hmm, this makes sense, but why does the initial fetch then update my
local branch and if I call subsequent fetches without the "-r" it will
fetch new revisions and update my local branch.
