That's precisely it, I'm use an old-school setup, Vi + make, and my idea
would certainly be helpful in this case.

I understand that these are the main benefits of out-of-source builds in

source directories. I'm not against it, quite the contrary. I just want
to make out-of-source builds "feel" like "inside-source" builds.
