+  There is one other effect of word splitting which differs between ksh
+  and zsh.  In ksh, the builtin commands that declare parameters such
+  as tt(typeset) and tt(export) force word-splitting not to take place
+  after on an assignment argument:
+  verb(
+    typeset param=`echo foo bar`
+  )
+  in ksh will create a parameter with value mytt(foo bar), but in zsh will
+  create a parameter tt(param) with value tt(foo) and a parameter tt(bar)
+  whose value is empty.  Contrast this with a normal assignment (no
+  tt(typeset) or other command in front), which never causes a word split
+  unless you have tt(GLOB_ASSIGN) set.  From zsh version 4.0.2 the option
+  tt(KSH_TYPESET), set automatically in compatibility mode, fixes this
+  problem.  Note that in bash this behaviour occurs with all arguments that
+  look like assignments, whatever the command name; to get this behaviour
+  in zsh you have to set the option tt(MAGIC_EQUAL_SUBST).
