For those who are curious, it's commit dce35658 from Feb. 9, +2012. Interestingly, the commit message is + + Output text from external commands in the article buffer + + * gnus-compat.el: Define `timer-set-function'. + + * mm-decode.el (mm-display-external): Output the text from the command + in the buffer after the command finished. This makes text-based + commands behave better. + +which says nothing about the complete restructuring of the timer +handling, which further reinforces my suspicion that the behavioral +change was unintentional.
