doc: Update note about source code formatting

petere · petere · commit b4d615aaa1ec · 2019-09-26T10:52:19.000+02:00
Update the note about why not to use // comments, even though it's now technically supported. The note about variable declarations was dropped here because it's addressed more properly later in the chapter.
