[help-gengetopt] enums for string values

from time to time I run into the same situation to lookup string values in 
gengetopt generated arrays (you know _values postfixed variables with "/* 
Possible values for ...*/" comment) to map user-given parameters into integer 
value, that is, the index of the array.

It would be nice if enums were generated beside string arrays (in the same 
order) and these enums were also set be cmdline parser. 
The corresponding *_given could store the enum value in case of simple (not 
multiple) option if enum offsets start from 1 instead of 0. I don't know what 
to do with multiple options now. (Of course, a very new tag in the cmdline 
structure would be the most convenient solution.)

A little example w/ cmdline.ggo:
option  "string-option" s "bla-bla" typestr="LEVEL" 
values="off","normal","high" default="normal" no

char *cmdline_string_option_values[] = {"off", "normal", "high", 0} ;   /* 
Possible values for string-option.  */

enum cmdline_string_options {
/* cmdline_string_option_no_value = 0 -- do we need it? */
cmdline_string_option_off = 1,
