[PATCH] D133674: [Lex/DependencyDirectivesScanner] Handle the case where the source line starts with a `tok::hashhash`

[Jan Svoboda via Phabricator via cfe-commits]

Could you explain why this is necessary and even correct? I'd expect Clang to give an error when seeing `##` in this position, and I'd expect the scanner to do the same.
