The colors in GHCI are awesome, really. But under Ubuntu 13.04, GHCI 7.6.3, I've got an issue: sometimes GHCI stops evaluating. First, it seemed to occure at irregular intervals. But then I found a way to get it broken any time:

in ghci-color, I enter:

[1..]

The evaluation does not end (no printout at all, which is wrong). When I hit Ctrl-C twice, it stops, and GHCI-prompt comes back in scope. But then it keeps broken somehow - I can't evaluate anything anymore, e.g.

1+2

doesn't get any result. Would be great if there would be a way to shift around this... Probably, it is related to gnome-terminal somehow.

My bash environment settings:

COLORTERM=gnome-terminal

TERM=xterm

_terms ()
{
COMPREPLY+=($( compgen -W "$( sed -ne 's/^([^[:space:]#|]{2,})|.*/\1/p' /etc/termcap 2>/dev/null )" -- "$cur" ));
COMPREPLY+=($( compgen -W "$( { toe -a 2>/dev/null || toe 2>/dev/null; } | awk '{ print $1 }' | sort -u )" -- "$cur" ))
}

The -e flag in the echo -e commands appears to be leaking into the output, like so:

$ ghci-color
GHCi, version 7.6.3: http:-e /-e -e /-e www.haskell.org-e /-e ghc-e /-e   :? for help
Loading package ghc-prim ... linking ... -e done.-e 
Loading package integer-gmp ... linking ... -e done.-e 
Loading package base ... linking ... -e done.-e 
Prelude> 

With the flag removed, I still see colored output but no trailing -es:

$ ghci-color                             
GHCi, version 7.6.3: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Prelude> 

Note that when I enter the following directly in my shell, hello, world is colored (even with the -e flag omitted) but no -e is visible:

$ echo -e '\033[92mhello, world'
hello, world

A very minor issue (that I've fixed on my end anyway), but perhaps you'll know the reason for it off the top of your head.

I need to type 'stack ghci' to enter REPL.
