 It turns out that if there is a tab character in
 {{{compiler/ghc.cabal.in}}} then the build fails in a way that I at least
 found hard to diagnose.  Since the configure script builds
 {{{compiler/ghc.cabal}}} from {{{compiler/ghc.cabal.in}}}, life would be a
 lot simpler if the build fell over at that point with an error saying that
 tab characters are forbidden in that file.

 Since I believe the tab character is a tool of Satan, I would not dream of
 suggesting that the configure script run expand(1) over the offending
 file.
