I don not have the code in front of me but I think they are just my mistakes.
I will take a look shortly.

Maybe it would be nicer to put a newline after the ||, to have the whole

Does it not work just to put the string up on the line before with the

Not sure why this is an improvement. It looks like it was already aligned

It doesn't look like this is aligned, but I didn't try applying the patch.

I think that the email format or the patch does not show the tabs in
the proper way.
I remember that there were some off by one alignments and this and the
previous one belong to them.
Nevertheless, I will take a look.

OK, quite possible. But it is strange that all of the function calls look
fine with their added and removed lines, and all of the function headers
look wrong.

It's very strange but the alignment seems proper when the patch is
applied. I really do not have an explanation for the email format.
I verified it, made the other changes suggested and resent it.

Yes :)

If you have removed the undesired changes, then I think you can just leave
the patch as is. Actually, Coccinelle isn't really designed for doing
whitespace changes, because it knows nothing about the whitespace in the
original code. It is just sort of a hack that it can actually be helpful.

The outer parentheses are not necessary. Parentheses in column 0 are for
the case where one wants to consider a collection of possible options, but
that is not your case here.
Also, with your rule, you remove the expression e and add it back. When
you do that, Coccinelle decides how to format e. In this case it probably
doesn't matter, because there is not much choice about the formatting, but
if you wanted to only remove the parentheses, the rule would be:
&
- (
e
- )

No, I think it's OK as is. In your particular case, it has no impact on
the output, and the semantic patch you give is understandable. It's just
something to remember for the future. Also, it's really a tradeoff.
Sometimes it is good to not remove things and put them back, because the
developer already made good choices about the spacing. But other times,
when your semantic patches makes big changes around some code, the code
will have to be reformatted anyway, and it can be easier to just let
Coccinelle do the whole thing. So it may be useful to try both ways, and
see what makes the largest amount of code look best.

Actually, Coccinelle doesn't care about the spacing that you put in the
semantic patch. So your - lines match all | operations, not just the ones
that are missing spaces. If you give the argument --smpl-spacing, then
Coccinelle will follow the spacing that you specify for the added code.
Without this option, it just does what it considers to be best, which
turns out to be what you want anyway.
