Shared hosting Apache PCRE .htaccess file for personal MediaWiki websites

A shared hosting based Apache PCRE public_html/.htaccess file for a website with the common features:

1. MediaWiki based (most of the website interaction is backendish --- there barely are any frontend behaviors anywhere)
2. Unlike most MediaWiki websites, doesn't have a url directory such as example.com/wiki/SOME_COMMON_WEBPAGE
3. Relevant visitors to it should always be redirected from HTTP to HTTPS and from WWW to NON-WWW

Code to review (apparently works after more than two testings)
