RFR: 8207190: JDK 11 javadoc generates bad code example

[Priya Lakshmi Muthuswamy]

Hi,

Kindly the fix for https://bugs.openjdk.java.net/browse/JDK-8207190
webrev : http://cr.openjdk.java.net/~pmuthuswamy/8207190/webrev.00/

This issue was caused as part of the fix for JDK-8187288 (bad (no) 
wrapping for modifier and type column)
When the method has lots of modifiers and arguments, the method 
signature gets very long doesn't fit within the page.
Instead of changing the white-space property in the pre tag of details 
section, changing it only for the method signature.

Thanks,
Priya
