Globbing with glob vs. pathlib

It might be worth mentioning that `glob.glob` and `pathlib.Path.glob` work slightly differently. `glob.glob` [treats dotfiles specially](https://docs.python.org/3/library/glob.html), while `pathlib.Path.glob` uses `**` [only to match directories](https://docs.python.org/3/library/pathlib.html#pathlib.Path), not files. It's easy to use `pathlib.Path.glob` without reading the docs closely enough to realize the differences from `glob.glob` and bash globstar behavior, and thus construct a pattern that doesn't match what you want.

Locate the guide section covering file globbing, then compare its existing explanation with the linked Python documentation for glob.glob and pathlib.Path.glob. Add a clear note about dotfiles and the different meaning of **, with examples or wording that distinguishes pathlib behavior from bash globstar behavior.
