I find the phrase "If non-empty braces are the only wildcard characters used in the glob" misleading because it makes it sound like there are many wildcard chars to choose from, rather than just * and braces.

There are a few other meta characters for glob().

META CHARACTERS
1.  \       Quote the next metacharacter
2.  []      Character class
3.  {}      Multiple pattern
4.  *       Match any string of characters
5.  ?       Match any single character
6.  ~       User name home directory
