svn2git question: error: unknown switch `t'

All,

I'm running the command svn2git -v --notags --branches REbranches <URL>

and I'm getting the following:

If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at 38b1da3... Update NEO targets to point to NeoMain kernel
Running command: git branch -t NeoMain@34 remotes/NeoMain@34
error: unknown switch `t'
usage: git branch [options] [-r | -a] [--merged | --no-merged]
   or: git branch [options] [-l] [-f] <branchname> [<start-point>]
   or: git branch [options] [-r] (-d | -D) <branchname>
   or: git branch [options] (-m | -M) [<oldbranch>] <newbranch>

Generic options
    -v, --verbose         be verbose
    --track               set up tracking mode (see git-pull(1))
    --color               use colored output
    -r                    act on remote-tracking branches
    --contains <commit>   print only branches that contain the commit
    --abbrev[=<n>]        use <n> digits to display SHA-1s

Specific git-branch actions:
    -a                    list both remote-tracking and local branches
    -d                    delete fully merged branch
    -D                    delete branch (even if not merged)
    -m                    move/rename a branch and its reflog
    -M                    move/rename a branch, even if target exists
    -l                    create the branch's reflog
    -f                    force creation (when already exists)
    --no-merged <commit>  print only not merged branches
    --merged <commit>     print only merged branches

Where did the -t come from?  What is this telling me?

Thanks much.
