I think auto-fill-mode is convenient for editing normal text but not
so much for source code (can give unwanted behavior) so I would
suggest to turn that off again and then when your line starts to get
long just hit M-q to get "##' " at the start of the wrapped lines. You
can also do C-c C-o to "clean" a the whole roxygen entry to wrap all
lines and update @param fields from the function definition.
