Fix the pattern used by comment-motion mappings to match the start of a
block comment.
Block-comment start lines were being ignored if the previous line
contained a double-quote character anywhere in the line. Line comments
should only be ignored if the previous line is a full-line comment and,
therefore, part of the current block comment.
