remove_query_arg messing up some URLs

[lumpysimon]

I'm using remove_query_arg to strip utm campaign parameters from user-submitted URLs, but for some URLs it is replacing dots with underscores.

E.g. if you pass ​http://www.nanowerk.com/news2/newsid=28843.php into this:

$url = remove_query_arg( array(
	'utm_source'
	'utm_medium',
	'utm_campaign',
	'utm_term',
	'utm_content'
	), $url );

it returns ​http://www_nanowerk_com/news2/newsid=28843.php

ticket:23284:23284.2.diff​ would fix this.

The URL appears to be invalid though, per ticket:23284:3. Shouldn't it be ?newsid=28843.php rather than newsid=28843.php?

No, that's the correct URL, but I agree it does look odd. If you go to their homepage you'll see all their URLs are in that format.

Duplicate of #23284.

This is fixed as of [24444] and [24445].
