A helper function that takes the contents of a commit object and finds its subject line did not ignore leading blank lines, as is commonly done by other codepaths. Make it ignore leading blank lines to match. * js/find-commit-subject-ignore-leading-blanks: reset --hard: skip blank lines when reporting the commit subject sequencer: use skip_blank_lines() to find the commit subject commit -C: skip blank lines at the beginning of the message commit.c: make find_commit_subject() more robust pretty: make the skip_blank_lines() function public
