* glob.c: New file.

(glob_wrap, glob_init): New functions.
(errfunc_thunk): New static function.

* glob.h: New file.

* txr.c (main): call glob_init if HAVE_GLOB is defined.

* configure (have_glob): New variable.
(gen_config_make): Add have_glob to config/config.make.
Detect glob function and set have_glob, and add
HAVE_GLOB to config/config.h.

* Makefile (OBJS): Include glob.h if have_glob is "y".

* genvim.txr: Scan glob.c for functions and variables also.

* txr.1: Documented glob and glob-related variables.
