Arglists should be '([] [coll] [coll x] [coll x & xs])
Docstring should mention "(conj coll) returns coll" and "(conj) returns an empty vector", and also the fact that "hence it can be used as a reducing function", clarifying the reason to use [] as the default.
I would like to accept this patch, but I need a signed CA and a properly formatted patch.
This ticket appears to be a duplicate of CLJ-2169, which also has a patch attached (dated 2017-05-27; the 0002 patch handles both :doc and :arglists) and is currently marked "Triaged" (also since 2017-05-27).
