RFR 8062647: Wrong indentation of arguments of annotated methods

[Ivan Gerasimov]

Hello everybody!

I noticed that the javadoc tool may produce the doc with misaligned 
arguments of annotated methods in the 'method details' section.
For example:
http://jre.us.oracle.com/java/re/jdk/9/nightly/latest/docs/api/java/util/EnumSet.html#of-E-E...-

Would you please help review the fix?
