Let's burn some cycles on this while the holidays give me time to do so.
"software development taste" is another term for "coding style". In
every project battles are fought over this between friends and foes. I
have never seen much evolution going on in this area.

I had to  take a look at this particular patch and I have to say that I
don't see, using your favorite term, evolution at work. It looks more
like the result of inbred. What the patch tries to do is avoid the extra
'if (err)'. Setting coding style aside, the question is whether there is
a good metric for the patch. So does it really safe processing time? Did
you look at the resulting assembly code for different target architectures?

You got pushed back on the change so you have to come up with solid
arguments for your change instead of spewing ideas about evolution in
software development. Running Coccinelle is one thing, but understanding
the results and what you are ultimately proposing to be changed is more
