Post #2974853

@liw@toot.liw.fi it's probably not optimally efficient, but I'll sometimes start by boxing out the lifecycle of the program: that is, I'll read the diff of the most recent commit to see what's still being worked on, then I'll go back and read the full contents of the initial commit to get a feel for the first working version. Then I gradually fill in the gaps with one or more other reading strategies depending on the codebase.
