Re: [RFC/PATCH] Implement git-cp.

If you touch builtin-mv.c already, why not just move cmd_cp() in there?  
It's not like it would be the first cmd_*() function living in the same 
file as other cmd_*() functions.

Why do we even want "git-cp", especially when git-mv and git-rm
are already pretty much redundant commands?

Especially, why do we even encourage copy-and-paste?
