Subject: use putStrLn instead of Haskeline's outputStrLn
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=521d83d05fe7147afa0ee9c91ff89242f180f3b2

use putStrLn instead of Haskeline's outputStrLn
use of the latter caused problems for Claus Reinke's macros that
redirect stdout.
