JavadocParagraph: allowNewlineParagraph should allow '\n' after P tag and content start from new line

[romani]

https://checkstyle.org/checks/javadoc/javadocparagraph.html

allowNewlineParagraph Control whether the

tag should be placed immediately before the first word.
default = true

but it actually not works. See examples in web site.

Check does not allow new line by default. Implementation is not exact to allow new-lines only.

proposal:
Do not change name of property, and default value.
Consider it as huge defect and make it work where allowNewlineParagraph=true does not violate:

 * <p>
 * New line after tag.
