Path processors too greedy with URLs ending with sitemap.xml

Reroll of #2 📌 Path processors too greedy with URLs ending with sitemap.xml Postponed: needs info

The patch above won't work for 4.x version, because 'Variants' have been replaced with 'Types'.
Here is the correct one.

There is a typo within the patch from #2 📌 Path processors too greedy with URLs ending with sitemap.xml Postponed: needs info . The second comparison within the IF clause here should be 'sitemaps'
if (count($args) === 4 && $args[1] === 'sitemap' && $args[3] === 'sitemap.xml') {
Reroll of #2 📌 Path processors too greedy with URLs ending with sitemap.xml Postponed: needs info against latest 4.x-dev with fixed typo.

ProcessOutbound Case:

Create a view with the URL of foo/bar/sitemap.xml. Try to go to this URL and you will be redirected to /bar/sitemap.xml.

FYI, that's not how it works. Outbound processors cannot be the cause of a redirect.
