Quote from "7.4.1 Shell-style glob patterns" in [http://hgbook.red-bean.com/hgbookch7.html chapter 7] of the [http://hgbook.red-bean.com/hgbook.html hgbook]:
- The “⋆” character matches any string, within a single directory.
- The “⋆⋆” pattern matches any string, and crosses directory boundaries. It’s not a standard Unix glob token, but it’s accepted by several popular Unix shells, and is very useful.
