PATCH: completion for compressed ps|pdf files for gv

[Alexandre Duret-Lutz <duret_g@xxxxxxxxxxxxx>]

Hi,

gv can read compressed .ps and .pdf files, and I use this
feature every days, unfortunately Zsh was not aware of this.
The suggested patch below adds the -z option to _ps and _pdf to
complete compressed files and modify _gv to use it.  (This is
also related to wich #56485 on the Debian bug tracking system.)

Question: is it really correct to suppress that `_wanted' call
in _pspdf (since _pdf will provide the description)?
