Hello!

Thanks for the PR. Could you please separate this into two separate commits? One for the typo fix in file_io.c and another for the typo fixes in the test files.

In the commit messages, the first should be prefixed with "xz:" instead of "Docs:". We use the "Docs:" prefix when referring to changes to things like the README, man pages, INSTALL, etc. The second commit should be prefixed with "Tests:".

@JiaT75 Two separate commits or PRs?
