Hello,
	here is a bug report and a patch for zsh-3.0.2. First the description
of the bug:

	- run "zsh" (the bug happens even with with the "-f" flag and no
          /etc/zshenv)

	- define the "TRAPDEBUG()" function to be anything, eg:

		TRAPDEBUG()
		{
		  return 0
		}

	- enter (for this to be really useful, you would put
	  "set -o AUTO_PUSHD" and "export DIRSTACKSIZE=10" in eg ".zshrc")

			select dir in `dirs`
			do
			  eval cd $dir
			  break
			done

	- the bug is that the "break" in the above loop is not executed, so
	  that you have to exit the loop with a "^D", otherwise you remain
	  in the loop forever.

My analysis is that "doshfunc()" is called because TRAPDEBUG is set and
this function resets the "breaks" variable to 0 a bit too early. See below
for the patch I propose (I don't know if it will break something else.)
