Disclaimer: I'm not a native speaker, so not sure those are actually incorrect, and can't offer non-trivial suggestions.
I skimmed about 2/3rds of these and while I agree on the surface that probably 3/4ths of them are improvements they aren't clear enough wins to methodically go through and write up one or more patches.
There are a few areas that seem outdated that could use a good once-over in the sgml sources to clean up. For those I'd expect that I or someone else may go and write up actual patches.
This run-on presentation is off-putting. Even if actual patches are not forthcoming I would at least suggest one email per topic with the suggestions broken down into at least bugs (at the top) and non-bugs/improvements.
