Request to update message command description

[sergey]

I was trying to use message option variable functionaliy and found out that variable key must be placed directly under the message tag. But on the wiki it is placed under the option tag. See https://wiki.wesnoth.org/InterfaceActio ... message.5D Please update the wiki.

Incorrect:

Code: Select all

    [message]
      speaker=narrator
      message=_"Select unit"
      [option]
        message=_"Orcish Warrior"
        variable=unit_index
      [/option]
      [option]
        message=_"Orcish Slayer"
        variable=unit_index   
      [/option]
    [/message]

Correct:

Code: Select all

    [message]
      speaker=narrator
      message=_"Select unit"
      variable=unit_index      
      [option]
        message=_"Orcish Warrior"        
      [/option]
      [option]
        message=_"Orcish Slayer"
      [/option]
    [/message]

UPD. wiki says "either the index or the value of the chosen option will be stored in the specified variable". I expected the option index to start from 0, but it starts from 1.

UPD 2. Pitfall - option index corresponds to only visible options. I.e. index of the first visible option is 1, even if there are several hidden options before it (because of [show_if)].

UPD 3. If option image is omitted, then option value key is ignored #3980

Thanks. Most of this has been done by gfgtdf and me. Only remaining is UPD 2.
