Completion fortune databases

[crpb]

hey @okapia

in reference to #131 (comment)

One exception is the fortune completion. On my system, the database is /usr/share/games/fortune so singular for the final path component and you would need to exclude .dat files. compadd should suffice - it rarely makes sense to use _values with generated values. Could you perhaps verify the fortune command you use. The completion can perhaps try multiple paths. It might be simpler if you do a fresh PR for any further fixups.

i removed the -S and hope that .../fortune(|s) .. is ok so. with a simple .../fortunes? ... it didn't work.

FYI, this is how it looks here on debian

% dpkg -S /usr/share/games/fortunes/
