note 113811 deleted from function.preg-quote by aharvey

Note Submitter: ewering at gmail dot com ---- WARNING WARNING WARNING - this function does not work as you expect! If you expect it to simply make any string you want to replace "harmless" no matter what characters it contains, it does NOT do this! I had to learn this the hard way by losing two hours of work in my web-based IDE which contains server-side PHP code for global Search & Replace in a project, and when a string I wanted to replace contained '/', it errored, causing random lines of code all over my project to be DELETED! AGAIN: This function does NOT quote every character that has a special meaning in a Perl regex, DESPITE THE DOCUMENTATION!
