Comment (by ryandesign):

 Replying to [comment:9 mf2k]:
 > The attached patchfiles should follow the standard naming convention and
 prepend "patch-".

 I'm happy as long as the local patchfile names end with ".diff" or
 ".patch". Eventually I'll get around to relaxing `port lint` to match
 that.

 Replying to [comment:10 ajdudman]:
 > My answer to comment:9 is all current patches should be removed, unless
 you know a way to set patch.pre_args on a per patch basis.

 `patch.pre_args` applies to all of a port's patchfiles. All patchfiles
 must use the same `-p` setting.

 > I would be most happy for patches to follow standard naming convention,
 but three out of six of the patches are sourced from git.archlinux.org
 with different, non-standard names.

 Names of patchfiles we're downloading from remove servers are obviously
 not under our control so whatever their names are is fine.
