The Wancho script is added to Emacs this time.

Also can we add something like this to etc/HELLO:

"Some of these greetings or the script name may be wrong or misspelled so if you know the script, please help by correcting them."?

For many of these languages/scripts it is difficult to find their greetings and most of the time if their greetings are available online they are in the roman script so often I have to convert them into their native script therefore these greetings may have a high chance of misspelling or they may be wrong altogether so adding something like the above mentioned line may help.

Thanks
