confirmed even when forcing no color, e.g

  $ export DFLAGS="-color=off" && ./build.d > a.out

then the error message contains control characters.

I've found a dubtful assulmption in build.d

https://github.com/dlang/dmd/blob/25e9247535649606e312f9e623be7a68b8d46678/src/build.d#L151-L157

"Since we're ultimately outputting to a TTY,"

                      ??????

"auto" should be the default. "auto" detects if the stuff is piped or not.
