Yes, it was done that way intentionally (about 14 years ago!).
I don't think it would be a good idea to change it and break
existing code. I feel it's better to be "permissive" about 
output formatting. If the output looks wrong, people can 
trace it back to the printf statement fairly easily,
and correct it.
