sort_help should be honoured by switches/flags

[pdf]

My quick hack just to get it working is here: pdf@d9a1919

Don't know if you want to organise it some other way...

Thanks for submitting. I'll look into it. I'd probably want a test to make sure it was working, but that's easy enough for me to do.

Used your commit as inspiration - this is in 2.5.0. I had it follow the setting for help command sort that exists. Hoping nobody wants separate control over the two, but we can always add it!

Thanks!
