Today I learnt that A* doesn't work for an arbitrary non-planar graph, you need additional structure: https://stackoverflow.com/q/26568552/509706 This matches my experience with difftastic so far. The graph is non-planar and my best heuristic only matches Dijkstra perf in typical cases.

I'm amused (and kinda surprised) to learn that shells have their own equivalent of blink tags, a blink escape code! https://stackoverflow.com/questions/17439482/how-to-make-a-text-blink-in-shell-script Seems equally annoying, I can't see a good use for it.

Found some outdated elisp on stackoverflow and fixed it, but saw it had been copy-pasted on assorted repos. Code has a half-life sometimes.
