This sounds weird, as ANSI colour controls do not differ among 
terminals. What if you set TERM=cygwin or unset TERM before `winpty mvn`?
What's even weirder is that I cannot even reproduce the test case, as 
`winpty mvn` tells me "Could not start 'mvn.exe': The system could not 
find the file. (error 0x2)", although `mvn` works.
