repro case

Building my code with clang -Wdocumentation is causing clang r279749 to assert
on me:

Assertion failed: (Content.size() != 0), function parseParagraphOrBlockCommand,
file /Users/builder/llvm/llvm/tools/clang/lib/AST/CommentParser.cpp, line 561.

I used creduce to create a small test case, attached.

To repro:

clang -fsyntax-only -Wdocumentation parseParagraphOrBlockCommand-assert.cpp 

This used to not crash, but I did not regress it.
