Move print_commit_summary() from builtin/commit.c to sequencer.c so it can be shared with other commands. The function is modified by changing the last argument to a flag so callers can specify whether they want to show the author date in addition to specifying if this is an initial commit. If the sequencer dies in print_commit_summary() (which can only happen when cherry-picking or reverting) then neither the todo list nor the abort safety file are updated to reflect the commit that was just made. print_commit_summary() can die if: - The commit that was just created cannot be found or parsed. - HEAD cannot be resolved either because some other process is updating it (which is bad news in the middle of a cherry-pick) or because it is corrupt. - log_tree_commit() cannot read some objects. In all those cases dying will leave the sequencer in a sane state for aborting; 'git cherry-pick --abort' will rewind HEAD to the last successful commit before there was a problem with HEAD or the object database. If the user somehow fixes the problem and runs 'git cherry-pick --continue' then the sequencer will try and pick the same commit again which may or may not be what the user wants depending on what caused print_commit_summary() to die. If print_commit_summary() returned an error instead then update_abort_safety_file() would try to resolve HEAD which may or may not be successful. If it is successful then running 'git rebase --abort' would not rewind HEAD to the last successful commit which is not what we want.
