In my opinion, per-topic patches would much better match the "please upstream 
patches" rule. Patches fixing bashisms, Linuxisms etc. are often spread across 
several files. Sometimes, patches to one file fix different things that ought 
to be upstreamed as seperate issues. Upstream may release with one issue fixed 
and others not.
Othoh, upstream patches (like fixes/enhancements not yet incorporated into a 
release) may also spread across different files (and not be available as a 
downloadable patch).
