JavadocParagraph allows new line before the next paragraph

[pbaranchikov]

http://checkstyle.sourceforge.net/config_javadoc.html#JavadocParagraph
created base on requirements of http://google.github.io/styleguide/javaguide.html#s7.1.2-javadoc-paragraphs

According to documentation:

Each paragraph but the first has <p> immediately before the first word, with no space after.

I could have <p> tag, followed by new line. Text is continued from the next line, so the tag is not "immediately before the first word"

/**
 * First paragraph.
 * 
 * <p>
 * Second paragraph.
 */

Also, even spaces are not violated:

/**
 * First paragraph.
 * 
 * <p> Second paragraph.
 */

good point, I do not see any reference in code that it do validation for that, completely missed functionality.
