yaml2obj might crash on invalid input when unable to parse the YAML. Recently a crash with a very similar nature was fixed for an empty files. This patch revisits the fix and does it in yaml::Input instead. It seems to be more correct way to handle such situation. With that crash for invalid inputs is also fixed now.
