ztat() blindly tries both escaped and unescaped names which sometimes may lead 
to funny results:

localhost% ls -F
\*  \\\*/
localhost% l \\\*/
\\\*/      \\\\\\\*/

both are marked as directories because first time it checks escaped \* and 
finds another one (which is directory now).

I am mostly concerned with unpredictable side effects with multibyte character 
sets.
