store flag value twice in command file

[danielb2]

using version 1.4

if I run progname initconfig the value for flag :value is stored twice

#!/usr/bin/env ruby
require 'gli'
include GLI

config_file '/tmp/cfg.yml'

desc 'specify a value to use.'
default_value 'value shows in cfg file twice'
flag [:v,:value]
arg_name 'value'

desc 'command to show default values dont store for command flags'
command :command do |c|
  c.desc 'command value'
  c.default_value 'will not store in cfg'
  c.flag [:o,:other]
end
exit run(ARGV)

show help output that default value is set correctly

show it being stored twice in cfg file. once for :v: and once for :value:

 cat /tmp/cfg.yml 
--- 
:v: value shows in cfg file twice
:value: value shows in cfg file twice
commands: 
  :command: {}

Yeah, this is somewhat annoying and could create problems. I think the expected behavior would be to use the long-form option if one is there.

which one would be selected for

flag [:u, :use_underscore, :'use-underscore'] ?

maybe adding something like flag_aliases could be useful.
