Gilles commented on MATH-485:
-----------------------------

It's a pity that Eclipse would automatically reformat a whole existing file! As 
people quite possibly use different editors and formatting tools, this could 
lead to flip-flop of formatting changes...
Seeing what comes out of the template you have used, it seems best to do the 
formatting by hand.

CheckStyle was not complaining about empty lines but lines that end with one or 
more space characters. Again a single space after the '*' character in a 
Javadoc comment is probably automatically created by Eclipse. Maybe the 
CheckStyle rule should be relaxed to allow trailing spaces in comments...

I think that an 80-character line should not be a hard limit. If there remains 
only a few characters to finish a statement, I prefer a longer line.
When the line is really going to be too long, I always try to figure out a 
layout that will not be too "unnatural".
