Trailing colon on GHC_PACKAGE_PATH doesn't work with ghc-pkg.
|Reported by:||cjs||Owned by:||simonmar|

According to section 126.96.36.199 of the Users' Guide, appending a colon to GHC_PACKAGE_PATH should include the system libraries, and this can be verified with ghc-pkg. While the colon does appear to work for ghci (as verified with -v), it does not appear to work for ghc-pkg.
