yep, everything is escaped as needed. I know that by looking at the 
debug output:
debug1: Sending command: ls <path to file I care about>

I've also printed the command to stdout and pasted it into a windows 
cmd shell and cygwin terminal with success.

If I use system("<cmd>"); instead of `<cmd>`;, the command returns 0, 
(no hang).  Unfortunately system wont work for my needs, as it is 
critical I evaluate stdout:stderr.

I do appreciate your help.
Stephen
