It breaks xsel expansion

[lilydjwg]

When pressing Tab, command will expand. xsel wants to fstat on stdin, and this script breaks that.

See this superuser question for details.

The problem is that xsel(1) itself is emitting the error when this plugin is loaded, not that this plugin somehow breaks TAB completion on backticks:

$ xsel
fstat error on stdin: Bad file descriptor

Nope, I was wrong, but I found the actual problem this time: the _zsh_highlight_bind_widgets() function is rebinding all ZLE widgets to make them invoke _zsh_highlight(). During this process, it somehow breaks backticks expansion.

That function, which was copied directly from the zsh-syntax-highlighting plugin, has not changed since. So this bug should also exist in the zsh-syntax-highlighting plugin!

[sunaku]

I was correct; the bug also exists in (and originates from) the zsh-syntax-highlighting plugin:

master ~/.zsh/bundle/zsh-syntax-highlighting> zsh -lf                                                          3:24PM
hostname% echo 'it works!' | xsel -pi      
hostname% echo it works\! 
it works!
hostname% source zsh-syntax-highlighting.zsh 
hostname% echo `xsel`xsel: fstat error on stdin: Bad file descriptor
echo

I'm not able to reproduce this issue anymore (xsel runs fine now) in my current environment:

$ zsh --version
zsh 5.0.5 (x86_64-pc-linux-gnu)

$ xsel --version
xsel version 1.2.0 by Conrad Parker <conrad@vergenet.net>

$ cat /etc/issue
Ubuntu 14.10 
 \l

Please re-open this issue if you're still able to reproduce this problem. 👮
