12b29ad2 - Editorial: Simplify `ready` (#1136)

Editorial: Simplify `ready` (#1136) (This change doesn't affect any behavior.) The previous structure for the `ready` algorithm involved a recursive path through an "else" branch. This tended to obscure the fact that the corresponding branch was *not* recursive and that the following steps were indeed reachable. Re-factor the algorithm to include fewer total branches and to contain the recursion more tightly.
