Thanks, and for catching the isremote() fix.
I adhoc tested against a variety of symlink and mountpoint reparse
points. I dont see any issues, and changes are working as expected.
I will keep watching the dev and patch mail lists for a while, but if
some issues pop-up then feel free to contact me directly.
