Fair points, though I'm not certain "will certainly get fixed up later"
is a given. Certainly indenting and basic style is a mechanical problem
that could be tested pre-commit hooks, and there should be no reason to
bike shed that on the list at all.
Grammar probably needs more serious consideration for protocol doc than
elsewhere due to its potential impact on compositor implementors - but
ever there probably not to the degree we're seeing lately.
Follow up commits that do nothing but change style and grammar can make
"git blame" less useful (when trying to figure out who would best review
a piece of code - not just "arrrrgh who wrote this stupid bug") and
provide churn for very little benefit, imho.
While we're drifting just slightly off topic here, I'm also concerned
about the basic usage of some of our tags:
Reviewed-by: indicates rigorous technical review *AND* a firm
conviction that the feature is important and should be included.
Acked-by: Indicates a firm conviction that the feature is important and
should be included, but no rigorous review has taken place.
Signed-off-by: Indicates an assumption of responsibility for the code.
I've seen a lot of Reviewed-by that I think is just "I looked at the
spelling and you're good to go". I'm starting to find this disconcerting.
(Sorry to sidetrack your thread Miguel! None of these complaints apply
to you at all!)
