htmltidy build 4th August 2000 uses stderr, exec output looks for stdout

I downloaded the source from the sourceforge page, and in its source when you run the control with -v it doesnt produce any output onto the standard output, instead it all goes to stderr. To make it work one needs to append '2>&1' to the command, after the escapeshellcmd() has ran.

I am not sure if there is a newer tidy release that has this otherwise, but if someone else has this problem this is the solution.
