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
