From a3f446a86fed6f3f70daef91b7f7cb5db4ebd383 Mon Sep 17 00:00:00 2001 From: Michael Pratt Date: Thu, 20 Aug 2020 13:28:43 -0700 Subject: Consistent precondition formatting Our "Preconditions:" blocks are very useful to determine the input invariants, but they are bit inconsistent throughout the codebase, which makes them harder to read (particularly cases with 5+ conditions in a single paragraph). I've reformatted all of the cases to fit in simple rules: 1. Cases with a single condition are placed on a single line. 2. Cases with multiple conditions are placed in a bulleted list. This format has been added to the style guide. I've also mentioned "Postconditions:", though those are much less frequently used, and all uses already match this style.
