New Revision: 115444

URL: http://llvm.org/viewvc/llvm-project?rev=115444&view=rev
Log:
When providing a block literal as a code completion for a
function/method argument, include the parameter name and always
include parentheses (even for zero-parameter blocks). Otherwise, the
block literal placeholder '^' can look very weird.
