Re: [gentoo-portage-dev] equery: deprecate --category filtering in belongs

[Brian Harring]

patch attached against 0.2.4.2-r1; rough stats follow;

full cold cache

That particular cold cache is a *full* cold cache; not the best test 
imo since most users have at least some chunks of portage 
configuration/python cached.


Cold cache, with equery --help primer to warm the cache; CONTENTS 
(what belongs operates on) is still out of the cache however making 
this a bit more likely use scenario.

Pretty heavy difference, no?

Mind you this isn't multiple runs, so the numbers are rough 
approximations- that said they're fairly representative.

Strongly suggest y'all keep category support (although I'll keep on 
using pquery instead ;).
