%c{3} is used to output the last three elements of a name. I've enhanced
NameAbbreviator to recognize %c{-3} to drop three elements off the name on bug
49010. The Javadoc for EnhancedPatternLayout did not hint at the other
capabilities of NameAbbreviator and still had PatternLayout's @since tag, so I
updated those at the same time.
