The problem there is that you have to rethink your solution if you decide you want to turn your buffer manipulation into a reusable command. I like Emacs, but the easy transition from pipeline to shell script is a big point in pipelines' favor.

It's not really a problem, though. 9 times out of 10 shell one-liners are single use, and when they're not, I want something more readable than a one liner, anyway.
