New Revision: 287900

URL: http://llvm.org/viewvc/llvm-project?rev=287900&view=rev
Log:
Include a hint how to see all errors if error is truncated.

This patch changes the error message from

  too many errors emitted, stopping now

to

  too many errors emitted, stopping now (use -error-limit=0 to see all errors)

Thanks for Sean for the suggestion!
