why the language files of Emerald do not comply with Joomla standard?

Since Emerald 8 is free to download, so I made a test of Emerald 8 on Joomla 2.5.24.

To my suprise, the language files of Emerald 8 did not comply with Joomla standard!

The simple basic rule is:

Empty space character should NOT be included in the language key.

But, I can see many language keys in your English language files that contains empty space character. For example:

ADD TAX TO PLAN="Add tax to plan"
COUPON HAVE TO CONTENTS VALUE="Coupon have to contents value."
DEFAULT CURRENSY TO DISPLAY ON THE SITE="Default currensy to display on the site."
DISCOUNT AMOUNT HAVE TO BE SET="Discount Amount have to be set."
EXPIRE SUBSCRIPTION MESSAGE="Expire Subscription message"
FAIL SUBSCRIPTION MESSAGE="Fail Subscription message"
GRANT SUCCESS PAGE="Grant Success Page"
GRANT TO NEW USERS="Grant To New Users"
GRANT TO OLD USERS="Grant To Old Users"
...

There are too many lines like above.

Do you still use such a "non-standard" language file in Emerald 9 ? Since I can not download Emerald 9, I can not confirm this.

If you still use such a language file format, please correct this error as soon as possible. That is very bad !
