Hi,

      Insight 6.8 built under mingw fires an 'unknown command
ide_shell_execute' if you try to use help.

      Attached is a fix for this, registration of ide_shell_execute needs
to happen under mingw as well as cygwin.

      Also the ide_shell_execute command with 'open' as its operation
didn't work for me, whereas using "" (default action, equivalent to
double-clicking the file) did.

      I'm new to this business of sending patches around, let me know if
I've got anything wrong!

Dave
