problems in the process:
1. Quoting should work properly now. In particular, Chet's reported bash

2. A lot of memory that just wasn't being free'd after use is now freed.
This should cause make to take up a LOT less memory when dealing with
archive targets.
3. Give proper credit to Adam de Boor in a number of files.
