Zsh 5.9 Tab Completion Bug

[丁骆昌祺]

Steps to reproduce:
Type these commands in the terminal:
```
$ touch o-st o-te
$ ls o-
```
Now hit <TAB>, the terminal becomes:
```
$ ls o-T
```
Hit <TAB> again, the terminal becomes:
```
$ ls o-te
```

there is a few steps missing to reproduce this. At a guess most likely your matcher-list style has values that you dislike.

I have a vague memory that this was a bug that has been fixed a while
ago, possibly related to nocaseglob?

If this is appearing in 5.9 as reported, then the only related change
since the release would be workers/50325 ... either way as Eric
guessed it probably has something to do with matcher-list.

Ah, my mistake, I scanned the message body for version info and missed
the subject line.

50325 was about an off-by-one error in matcher-list comparisons.
Given that "s" is becoming "T", I'm betting that is in fact the
problem.

The problem exists in zsh-5.9 with
zstyle ':completion:*' matcher-list '' 'm:{a-zA-Z}={A-Za-z}'

It has been fixed by 50325.
