Thanks for the bug report.  I can reproduce this.

The solution is to add an ending slash to the remote path:

  ./sshfs -o transform_symlinks -o allow_root root <at> server:/ihome/ /ihome

The following patch fixes the I/O error, instead it will fail at mount
time, which I think is the correct behavior.

Thanks,
