ghci / ghc -e outputs terminal escapes even when redirected to file/pipe
When running the interpreter (ghc --interactive, ghc -e, or runhaskell) with stdout redirected to a file, pipe, or other non-tty, ghc sends some terminal initialization sequences. This can be reproduced in a KDE konsole window: ``ghc -e 'putStrLn "hi" >file'' will write an extraneous <escape>[?1034h to the file.
