OK.  You're right, your patch is definitely an improvement.

Wording the commit comment "Make `describe-function-1' give autoload
status and load file exactly once" or so would make the intent plain.

As long as I'm here ... I would prefer to have "loaded" become "will
load" in the case of an autoload.  And maybe it would be less
ambiguous to make the first line "`loop' is an /autoloading/ Lisp
macro".
