Hi,
It's very interesting. I have made a patch for it.
The -N (--nearest) option is available with the -S or -l option.
$ cd libutil
$ global -xl main # local search -> not found
$ global -xl main -N # nearest search
main 363 ../global/global.c main(int argc, char **argv)
main 198 ../gozilla/gozilla.c main(int argc, char **argv)
...
Would you please try it?
Regards,
Shigio
