I think it would be easier and far more productive to fix
README.Coding.  This rule causes way to much trouble, it would be far
more productive if the time spent enforcing it was spent on actual code
review, as the rationale is, in my view, entirely weak.

(Unlike the 80 column rule, which is to do with code nesting and
complexity, trailing white-space has zero impact on the code when
'cleaned up'). 

Finally, before someone suggests to 'just' have git clean it up, there
are times (our XML docs, LDIF files) where it is significant, so it
can't 'just' be stripped.

We do need focus on code style and quality in reviews, but while Jeremy
will again say something about M&Ms here, we have got to the point were
everybody looks for the M&Ms and never the rest of the code. 

Indeed Gary has got to the point where he jokes in the office that he
should put in a long line in the hope of attracting some comment!

Please review and push! 

Thanks,

Andrew Bartlett

Subject: [PATCH] README.Coding: Trim rules to things that actually impact on
 Samba

Some rules cause cause folks to flag code only for whitespace issues
rather than for the code found within.

Focus our rules on things that matter, so as to increase team harmony
and decrease pointless code churn.
