I'd like to expand the docstring of command `org-agenda-filter-by-tag` to document the Elisp equivalent of interactive prefix arguments. By trial and error and guesswork I determined that I could emulate `C-u C-u` by passing `'(16)` as the second argument (`strip-or-accumulate`). I'd like to add text explaining this, generalized to all prefix combinations.
I just thought I'd mention it on the list first, to get any thoughts and advice that might be useful. For instance, currently there is a paragraph for each prefix combination (`C-u`, `C-u C-u` and `C-u C-u C-u`). Should I add Elisp calling doco to each, or should I expand the subsequent paragraph that deals specifically with Elisp calling? I tend to favor the latter as least confusing, but that might be a matter of convention or opinion that others are better qualified to comment on. A further point: I already knew from prolonged usage that `C-u` combinations evaluate numerically as powers of 4, but a newbie might not. Should we explain this? I don't think it would be appropriate, but again I'm open to advice. If not, should we at least link to the explanation in the Elisp manual? I know we don't usually bother, but since outcomes differ substantively in this case, maybe we should here.
