Comment (by pierre.labastie):

 From the NEWS file in source dir:
 Changes from 5.3.1 to 5.4

 The 'exec' and 'command' precommand modifiers, and options to them, are
 now parsed after parameter expansion.  Previously, both the modifier and
 any options to it were parsed between alias expansion and parameter
 expansion (see zshexpn(1)), so they could neither be quoted nor be the
 result of parameter expansion.  Examples: 's=command; $s -V ls' and
 '\command -V ls' now work as expected.

 Functions executed by ZLE widgets no longer have their standard input
 closed, but redirected from /dev/null instead. That still guards
 against user defined widgets inadvertently reading from the tty device.

 There is an option WARN_NESTED_VAR, a companion to the existing
 WARN_CREATE_GLOBAL that causes a warning if a function updates a
 variable from an enclosing scope without using typeset -g.  It can be
 turned on for an individual function with "functions -W".

 zmodload now has an option -s to be silent on a failure to find a module
 but still print other errors.
