Glob expressions are easier than regexes to write correctly; they're often easier to read as well. We support all of the syntax in https://github.com/mrmlnc/fast-glob#pattern-syntax, which should provide more than enough flexibility for JSDoc users.
Related change: If a `package.json` or `README.md` file gets picked up as one of your source files, we no longer assume that it should be incorporated into the generated docs. Instead, you must specify the file explicitly with the `-P` flag (for `package.json`) or the `-R` flag (for `README.md`).
