If you switch to verbatim there are only about a dozen.

I think the odds of an accidental collision with badc0de are pretty low.

Each hex character represents 4 bits. That means that a 7 character string is 28 bits. That's about 268 million possibilities. On average, it would take around 134 million commits to get one that started with "badc0de".
