[clang-format] formatting of comment not stable; oscillates between two ways

[joelhock]

formatting oscillates between the two ways shown below each time it is reformatted with 19.1.0-rc3 and also main as of 114ff99. version 18 consistently chose the first one, fwiw.

.clang-format contents:

---
Language:        Cpp
IndentWidth:     4

MYMACRO(Val1,
        A, // a comment
           // a comment
        AA, // a comment
);

MYMACRO(Val1,
        A,  // a comment
            // a comment
        AA, // a comment
);

version 18 consistently chose the first one, fwiw.

Which version of 18?

[joelhock]

greatest apologies! this is not a regression; it has been this way since at least version 8 (the farthest back binary i have).
