The existing severities all used printDoc, which always adds a trailing newline, which we don't want for the GHCi messages. I therefore added a new severity SevInteractive, which doesn't add a newline. compiler/ghci/Linker.lhs | 9 +++++---- compiler/main/DynFlags.hs | 13 +++++++++++-- compiler/main/ErrUtils.lhs | 1 + compiler/main/ErrUtils.lhs-boot | 1 + 4 files changed, 18 insertions(+), 6 deletions(-) }}} -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7456#comment:2> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
