 * 'arg' is a possible argument string (taken only if option has an arg)
 * 'options' points to options structure to modify (can be NULL).
 * 'set'==0: set only in 'options' if it's given.
 * 'set'!=0: set global variable option.
 * return value: no. of fields taken (1 or 2), or 0 if option not found.

 * These combinations are used:
 *
 * glopt(name,arg,NULL,1): set global variable option
 * glopt(name,arg,NULL,0): parse over option
 * glopt(name,arg,options,0): set file local option
 * glopt(name,arg,&fdefault,1): set default file options
 * glopt(name,arg,options,1): set file local option
