But it is this "." in the default path that is the reason GHCi 
gives unexpected results, isn't it?  [See Hal Daume's original 
bug report]

Also, even if we have no implicit roots, an explicit "." in the 
search path might give rise to exactly the same problems.  This 
is only better than the current status in the sense that we can 
say "the programmer asked for it"...
