Please no '.' at the end of a tag (and sorting would not hurt).

I wanted to get a look at those, but I can't find them in coverity webui.
Maybe those issues have been closed, but then I can't look at them.. ?
Any help would be appreciated.

The commitlog indicates memory leaks, I am a bit surprised to see this change.
What is the rationale?
