Are you sure you've copied the code verbatim? Especially the quotation
marks? The output I get looks like:

'/home/ghost/bin' '/usr/local/bin' '/usr/local/sbin' .....

The quotation marks would allow me to figure out the empty element, and
so detect why it's there. I could just add code to filter out empty
elements, but if possible, I'd like to also know why there are present.

Neither do I. The only crazy idea I have is that %SystemRoot% expands to
nothing, but that would break too much.

BTW, since we seem to be in the same timezone, you might want to use more
responsive communication medium.
