confusing "Warning: Imported from"

[Simon Peyton-Jones]

Good point, thank you.  I've fixed this.

(Ian: I'm not certain that the patch will smoothly move to the branch,
but the same idea will apply there.)
	* Improve handling of unused imports (test is mod75)

| line 12 and 13 of my source ATC2.hs
| (http://hackage.haskell.org/trac/ghc/ticket/955)
| are:
| 
| > import HsName (HsName(UnQual))
| > import PropPosSyntax
| 
| UnQual comes in via PropPosSyntax and HsName but is not used.
| 
| However, I would expect a warning for my explicit import of UnQual
from
| HsName. Instead I get:
| 
| ATC2.hs:13:0:
|     Warning: Imported from `PropPosSyntax' but not used:
|                data constructor `UnQual'
| 
| Is this a known (or easy to resolve) issue?
