Nearly done.  There are whitespace errors in src/jdk.jcmd/share/man/jcmd.md and it doesn't match the new ClassesDCmd desc string.
Personally I like "Print all loaded classes." with the full stop and just "Classes may be annotated with flags.." as the current "Some classes" is really mysterious!
Thanks for making this help readable for the first time.

CSR looks good also. It could say that -location is a BOOLEAN argument, default false.  And maybe that it affects the new flags which can be shown.

I really like it when JBS issues or PRs (or both) include example output so people know what they're getting.
