Thanks! Didn't know this is copied as-is, I'll take better care
in the future. Hopefully the commit message of the attached patch is better.

The attached patch fixes the second issue, I tested with a dummy .so
in /usr/local/lib/zathura. Plugin file formats are now also made unique. 
Let me know if this can be simplified, or if it is in any case unneeded since the "uniqueness"
is implicit in the matching code later on - I'm still learning more and more about the wonders of zsh expansion,
and every bit I learn leaves me wondering how I could ever survive without that knowledge up to now. 

Cheers,
Oliver

Spotted very well, my font and mail client hid that from me. 
I did accidentally hit the keybinding for SCIM (Smart Common Input Method) while typing,
and it started to interfere. That created some funny characters, and apparently I missed to remove the
"g" once I noticed it.
