* glob(3) -- a superset of the one defined in POSIX 1003.2.
*
* The [!...] convention to negate a range is supported (SysV, Posix, ksh).
*
* Optional extra services, controlled by flags not defined by POSIX:
*
* GLOB_QUOTE:
* Escaping convention: \ inhibits any special meaning the following
* character might have (except \ at end of string is retained).
* 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
* not contain any magic characters. [Used in csh style globbing]
* 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
* gl_matchc:
* Number of matches in the current invocation of glob.
