e.g. "oracle callgraph <package>" Also: simplified error handling. Eliminated oracle.errorf because it prepends "file:line:col: " to the error message so the main function can't safely prepend "Error: ". The position wasn't interesting though: it was just -pos, more or less. R=crawshaw, dominik.honnef, r CC=golang-dev https://golang.org/cl/13864044
