REG master, control character in DMD output even if piped

Mon May 11 22:33:16 UTC 2020

just open a console in your terminal, put a typo in a source to 
get an error (for example line 792 of declaration.d, rename 
isOverDeclaration -> isOveDeclaration) and

   $ make -f posix.mak > a.out

I get things like

> ERROR: [1mdmd/declaration.d(792): [1;31mError: [mno property 
> [0;36m[m[1misOveDeclaration[0;36m[m for type 
> [0;36m[m[1mdmd[0;36m.[m[1mdsymbol[0;36m.[m[1mDsymbol[0;36m[m, did you mean [0;36m[m[1mdmd[0;36m.[m[1mdsymbol[0;36m.[m[1mDsymbol[0;36m.[m[1misOverDeclaration[0;36m[m?

Not good.
