Update inline-comments.md

According to the phpcs --standard=Joomla one should NOT have a single blank line before a comment or a block, if the comment is the first line of a code structure. (I.e, when the newline would appear after a '{' line, don't add it). Otherwise phpcs will complain with "Blank line found at start of control structure"
Update inline-comments.md

Added a visual example.
