This is due to our explicit AlignTrailingComments=false, it may make

Namely the inconsistency in reformatting from

void decl1(); // lengthy comment comment comment comment comment comment comment comment               // comment comment comment comment comment comment comment pertaining to decl1 void decl2() {} // lengthy comment comment comment comment comment comment comment comment                 // comment comment comment comment comment comment comment pertaining to decl2
void decl3();

to

void decl1(); // lengthy comment comment comment comment comment comment comment comment     // comment comment comment comment comment comment comment pertaining to decl1 void decl2() {} // lengthy comment comment comment comment comment comment comment comment // comment comment comment comment comment comment comment pertaining to decl2
void decl3();

treating comments following function definitions differently than those following mere function declarations.

It appears that changing AlignTrailingCommentst to true would solve that, and would reformat from

void decl1(); // lengthy comment comment comment comment comment comment comment comment
              // comment comment comment comment comment comment comment pertaining to decl1
void decl2() {} // lengthy comment comment comment comment comment comment comment comment
                // comment comment comment comment comment comment comment pertaining to decl2
// Comment pertaining to decl3:
void decl3();

to

void decl1();   // lengthy comment comment comment comment comment comment comment comment
                // comment comment comment comment comment comment comment pertaining to decl1
void decl2() {} // lengthy comment comment comment comment comment comment comment comment
                // comment comment comment comment comment comment comment pertaining to decl2
// Comment pertaining to decl3:
void decl3();

(and the changes it would cause to `solenv/clang-format/reformat-formatted-files` would appear to be OK, too).

I'm somewhat undecided whether or not to do that change to .clang-format now. My feeling is that reformatting of comments is a pain and a gotcha anyway.
