Use `clang::isHorizontalWhitespace` / `clang::isVerticalWhitespace` instead
(from Basic/CharInfo.h).

... because this case probably shouldn't get merged if the second comment is
not indented. It seems that the indentation is the only way we can tell that
case apart from:
int trdoxyB; // Not a Doxygen trailing comment.
// This documents trdoxyC, not trdoxyB.
int trdoxyC;
Perhaps we should only allow ordinary comments to merge with trailing comments
if they start in the same column. I'm not too happy about making the semantics
depend on the indentation, but you're already proposing that they depend on
whether there are non-whitespace characters earlier on the same line, so
perhaps that is OK.
