Wrong language string when installing Joomla

Install a clean master and choose install languages when you get to that page. Select or not languages in the list and proceed.
the following string will display:
INSTL_LANGUAGES_NO_LANGUAGE_SELECTED="Please, select a language. If you don't need to install other languages press the 'Previous' button"

This is wrong.

In fact we need 2 strings:
•  one to display if no languages were selected in the language list and Next was pressed,
INSTL_LANGUAGES_NO_LANGUAGE_SELECTED="No languages have been selected to be installed. If you need to install some languages, press the 'Previous' button and choose desired languages from the list."

•  and one when some languages have been installed, to let the users know they can install more.
INSTL_LANGUAGES_MORE_LANGUAGES="Press the 'Previous' button if you want to install more languages."
