 The input record separator, newline by default.  Works like B<awk>'s RS
-variable, including treating blank lines as delimiters if set to the
-null string.  You may set it to a multicharacter string to match a
+variable, including treating empty lines as delimiters if set to the
+null string.  (Note:  An empty line can not contain any spaces or
+tabs.) You may set it to a multicharacter string to match a
 multi-character delimiter.  Note that setting it to C<"\n\n"> means
 something slightly different than setting it to C<"">, if the file
-contains consecutive blank lines.  Setting it to C<""> will treat two or
-more consecutive blank lines as a single blank line.  Setting it to
-C<"\n\n"> will blindly assume that the next input character belongs to the
-next paragraph, even if it's a newline.  (Mnemonic: / is used to
