revert: simplify getting commit subject in format_todo()

Browse source 
format_todo() calls get_message(), but uses only the subject line of
the commit message.  As a minor optimization, save work and
unnecessary memory allocations by using find_commit_subject() instead.
Also, remove the unnecessary check on cur->item->buffer: the
lookup_commit_reference() call in parse_insn_line() has already made
sure of this.
