Comment (by mkoeppe):
I just tried `sage -f latte_int` and I observe the following three things
(this is with `MAKE='make -j12'` in case that matters:
- Sage banner in color, interleaved with environment variables in color
due to competing output
- a visible prompt "Are you sure you want to continue [Y/n]? "
- building the dependency 4ti2
- another warning about experimental packages, but no visible prompt.
