split across physical lines using a backslash). A backslash is
illegal elsewhere on a line outside a string literal.

\subsection{Implicit line joining\label{implicit-joining}}
Expressions in parentheses, square brackets or curly braces can be
lines. Implicitly continued lines can also occur within triple-quoted
strings (see below); in that case they cannot carry comments.
-\subsection{Blank lines\label{blank-lines}}
-A logical line that contains only spaces, tabs, formfeeds and possibly a
-comment, is ignored (i.e., no NEWLINE token is generated), except that
-during interactive input of statements, an entirely blank logical line
-(i.e. one containing not even whitespace or a comment)
-terminates a multi-line statement.

+A logical line that contains only spaces, tabs, formfeeds and possibly
+a comment, is ignored (i.e., no NEWLINE token is generated). During
+interactive input of statements, handling of a blank line may differ
+depending on the implementation of the read-eval-print loop. In the
+standard implementation, an entirely blank logical line (i.e.\ one
+containing not even whitespace or a comment) terminates a multi-line
+statement.
