Subject: Show CmdLineError exceptions as "<command line>: ..."
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=db0591be8928dbe75e8b804f2ae95728a6074b7e

Show CmdLineError exceptions as "<command line>: ..."
instead of something like "ghc-6.8.2: ...", which causes problems in
the test suite.  In any case, "<command line>" seems a more
appropriate context for these errors, the only question is whether
we're using CmdLineError incorrectly anywhere.
