I suppose that depends on whether the Makefile format the "make project" 
already includes a means to specify the search-path and the ignore 
patterns. Same for "cmake project" and CMakeLists.txt.

But if you're going to the VC project backend for all those projects 
anyway, the answer to the question won't make a difference.

So I suppose we could introduce those variables globally, but then say 
that the respective methods must use them, unless the project file 
includes syntax allowing the user to specify those values there.

There no solid plan on this, but I'd expect the functions on the left 
all start with project-. So M-x rgrep uses the current directory, and 
M-x project-rgrep uses the project-roots combined with 
project-search-path (maybe we'll have two commands for that: one won't 
include search-path, and another will).
