URL woes that never end

[Rudolf Adamkovič]

Greetings!

I lamented a while ago about URL handling in Org. To provide a concrete 
example, below is a shell script that Org does not export correctly to HTML. 
More specifically, Org considers the script to be a URL. Further, and 
amazingly, even if I change “see <URL>.” to “see <URL> to learn more”, Org 
*still* does not parse the URL correctly, even with a valid URL per RFC *and* 
surrounding angle brackets (<>) *and* spaces on both sides.
