wrapping anchor tags around a URL

[Richard K Miller <richardkmiller@xxxxxxxxx>]

I wrote a little function to put anchor tags around a URL.  We're  
using it to make URL's in paragraphs of text linkable:

function link_the_links($s) {
	return preg_replace('@(http://[^\s]+)@sm', '<a href="$1">$1</a>', $s);
}

Its only flaw (besides a goofy name) is that if a link comes at the  
end of a sentence, right before the period, the period ends up in the  
link, thus breaking the link.  I've got to somehow ignore the  
trailing period if it is present.

Any ideas?
