- Update to version 5.0.8
* Global aliases can be created for syntactic tokens such as command
separators (";", "&", "|", "&&", "||"), redirection operators, etc.
* There have been various further improvements to builtin handling
with the POSIX_BUILTINS option (off by default) for compatibility with
the POSIX standard.
* 'whence -v' is now more informative, and 'whence -S' shows you
how a full chain of symbolic links resolves to a command.
* The 'p' parameter flag now allows an argument to be specified
as a reference to a variable, e.g. ${(ps.$sep.)foo} to split $foo
on a string given by $sep.
* The option FORCE_FLOAT now forces variables, not just constants,
to floating point in arithmetic expressions.
* The type of an assignment in arithmetic expressions, e.g. the
type seen by the variable res in $(( res = a = b )), is now
more logical and C-like.
* The default binding of 'u' in vi command mode has changed to undo
multiple changes when invoked repeatedly. '^R' is now bound to redo
changes. To revert to toggling of the last edit use:
bindkey -a u vi-undo-change
* Compatibility with Vim has been improved for vi editing mode. Most
notably, Vim style text objects are supported and the region can be
manipulated with vi commands in the same manner as Vim's visual mode.
* Elements of the watch variable may now be patterns.
* The logic for retrying history locking has been improved.
- Remove gcc5-fix.patch, fixed upstream.
