instead of requiring all "short description" strings to begin with two spaces. This makes these strings less mysterious, and it fixes some cases where short description strings mistakenly did not begin with two spaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57521 91177308-0d34-0410-b5e6-96231b3b80d8
