- Update to zsh 5.3
* Unicode9 support, this needs support from your terminal to
work correctly.
* The new word modifier ':P' computes the physical path of the
argument.
* The output of "typeset -p" uses "export" commands or the "-g"
option for parameters that are not local to the current scope.
* vi-repeat-change can repeat user-defined widgets if the widget
calls zle -f vichange.
* The parameter $registers now makes the contents of vi register
buffers available to user-defined widgets.
* New vi-up-case and vi-down-case builtin widgets bound to gU/gu
(or U/u in visual mode) for doing case conversion.
* A new select-word-match function provides vim-style text objects
with configurable word boundaries using the existing
match-words-by-style mechanism.
* Support for the conditional expression [[ -v var ]] to test if a
variable is set for compatibility with other shells.
* The print and printf builtins have a new option -v to assign the
output to a variable.
* New x: syntax in completion match specifications make it possible
to disable match specifications hardcoded in completion functions.
