Hi everybody!

I am a bit surprised that GHC replaces 	"	Hallo" (I used a tab=20
here - used not coded ('\t').)
by					"        Hallo". (GHC replaced the=20
tab by 8 spaces.)
Is this a bug? Hugs keeps the tab.
(See  the attached code, and output from Hugs and GHC. I am using ghc-5=
.04 and=20
WinNT.)

Any comments?
Andreas
