Major changes between versions 4.3.5 and 4.3.6
----------------------------------------------
cd, chdir, pushd and popd now take a -q option to suppress side effects
including printing the directory stack (for pushd and popd) and executing
the chpwd hook functions (for all four).

The parameter subscript (e) flag now forces the argument to be treated
as a string where it would previously have been treated as a pattern,
for example ${array[(ie)*]} substitutes the index of the element whose
value is "*".
