GLOB_STAR_SHORT
When this option is set and the default zsh-style globbing is in effect, the pattern `**/*' can be abbreviated to `**' and the
pattern `***/*' can be abbreviated to ***. Hence `**.c' finds a file ending in .c in any subdirectory, and `***.c' does the
same while also following symbolic links. A / immediately after the `**' or `***' forces the pattern to be treated as the unab‐
breviated form.
