+ * Optional extra services, controlled by flags not defined by POSIX:

+ * GLOB_MAGCHAR:
+ * Set in gl_flags if pattern contained a globbing character.
+ * GLOB_NOMAGIC:
+ * Same as GLOB_NOCHECK, but it will only append pattern if it did

+ * GLOB_ALTDIRFUNC:
+ * Use alternately specified directory access functions.
+ * GLOB_TILDE:
+ * expand ~user/foo to the /home/dir/of/user/foo
+ * GLOB_BRACE:
+ * expand {1,2}{a,b} to 1a 1b 2a 2b
+ * GLOB_PERIOD:
+ * allow metacharacters to match leading dots in filenames.
+ * GLOB_NO_DOTDIRS:
+ * . and .. are hidden from wildcards, even if GLOB_PERIOD is set.
+ * gl_matchc:
