3.3.1.3.2 Character context continuation
If a character context is to be continued, the "&" shall be the last
nonblank character on the line and shall not be followed by commentary.
An "&" shall be the first nonblank character on the next line
that is not a comment line and the statement continues with the next
character following the "&".
