“The repetition of exposition in quotes went out with the Stanley Steamer:
Marion gave me a pain in the neck.
‘You give me a pain in the neck, Marion,’ I said.
This turns up more often than you’d expect.”
— “Theory and Practice of Editing New Yorker Articles,” written in 1937 (PDF)
Good to know, really.
Edited to add: TV Tropes kindly supplies a term for this.
