Dunno where the man page error stems from, but the official documentation
is correct:  http://cygwin.com/cygwin-ug-net/using-utils.html#strace

> actually turns off the child tracing

This is documented in http://cygwin.com/cygwin-ug-net/using-utils.html#strace
as well:

  -f, --trace-children         trace child processes (toggle - default true)

Fixed in CVS.  You now get

  $ mkdir dir
  $ find . -name dir -type d -exec rm -rf '{}' \;
  find: `./dir': No such file or directory

as on Linux.
