Whoa, why the negativity? Dude found a bug in CPython, fixed it, and had his patch accepted. Regardless of whether he fixed the bug that you wanted fixed or not, it's always good to have more eyes and hands on a project, especially if people are getting involved for the first time.

OP did have a patch submitted and merged into CPython right? You are talking as though all the OP did was to add a strip in the program.
