Merge branch 'jk/chopped-ident'
A commit object whose author or committer ident are malformed crashed some code that trusted that a name, an email and an timestamp can always be found in it. * jk/chopped-ident: blame: handle broken commit headers gracefully pretty: handle broken commit headers gracefully cat-file: print tags raw for "cat-file -p"
