Subject: z parameter expansion flag is broken?
From: Yuya Amemiya <ghostrevery@gmail.com>
X-Mailer: Mew version 6.7 on Emacs 24.5 / Mule 6.0
 =?iso-2022-jp?B?KBskQjJWOzZOJBsoQik=?=
Mime-Version: 1.0
Content-Type: Text/Plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

Why does z parameter expansion flag remove leading '-' from result?

in zsh 5.4.1

```
$ echo ${(z):--a}
a
$ echo ${(q):--a}
-a
```

in zsh 5.3.1

```
$ echo ${(z):--a}
-a
$ echo ${(q):--a}
-a
```

regards
