Re: config.site overrides commandline

| Sounds perfectly reasonable.  config.site is also loaded to late

|  1) check the command-line for --prefix
|  2) load config.site
|  3) check the rest of the command line

That's really fine.  Any candidate to implement it?

But I'd 3 is s/rest of the/whole/.
