Fixed

The patch needs a refresh, the current 45032.patch​ removes the end-of-file new line, all PHP files should have a new blank line at the end of the file

[AbdulWahab610]

I just rechecked pluggable.php it has two newlines at the end of the file. I removed the extra end line in my patch. I can resubmit the patch without changing the endline.

Ah, perfect, thanks @AbdulWahab610, the patch 45032.patch​ is fine as is then

The current use appears to be correct in that it's a contraction of "who is" rather than possessive.

That said, it could use some editing. :)

How about: "If $id matches the current user, there's nothing to do"

Moving to the 5.1 milestone
