Provided Hashes in errata.pdf Not Found

[jonaprieto]

While I was trying to verify the amendments listed in some entries in the errata.pdf file, I ran into a problem with the provided Git hashes. I was expecting to use some of these hashes with the git checkout command, but I keep receiving an error stating that the specified hash was not found.

Here is an example using just the first hash from the pdf found at https://hott.github.io/book/errata-1357-gbe0b8e2.pdf:

$ git checkout gb29ea2f
error: pathspec 'gb29ea2f' did not match any file(s) known to git

How am I supposed to use these hashes? what if I want to check the exact commit that introduced the change described by the entry in the errata?

You have to omit the "g"; the commit hash is just b29ea2f.

True, it got a bit late here, didn't see that.
