…se error Issue as described in 3736. The fixer would try to remove superfluous whitespace remaining after the move of the opening brace to the previous line, but did not take into account that there may not be any whitespace to removed, i.e. that the `$opener +1` token could be the same as the `$next` token. Fixed now. Includes unit test. Fixes 3736
If a return type declaration was not confined to one line, the sniff could have a fixer conflict with itself. The fixer would also potentially remove a close curly on the same line, causing parse errors. Fixed now. The diff will be most straight forward to review while ignoring whitespace changes. Includes unit tests.
