Yes, I will use the word "check" only in later version.

Fixes: lines don't need to have a "commit" prefix before the commit id, the description
in normal commit id could across multiple lines, and we don't need to consider the
$commit_log_possible_stack_dump for 'Fixes:' tag line. I mean it will make the GIT_COMMIT_ID
code become harder to read and maintain.
