But contrary to the markers printed by `nix-store --print-build-trace', these
show up during normal use (so it's kind of ugly).  It's worth noting that the
escape sequences printed by startNest/stopNest allows phase start/end to be
extracted.  In fact that's exactly what the build log pretty-printer
(nix-log2xml) does.
