Comment:

 0a2abb3780:

 The function comment change does not describe what the function now does:
 it only returns 0 or 1. And it says "renturn".

 4e720ad736:

 else has an extra space in:

 {{{
 +  if (a->git_tag_len)
 +     return fast_memcmp(a->git_tag, b->git_tag, a->git_tag_len);
 +   else
 }}}
