Add missing help text to taxonomy_help() for adding/editing vocabs/terms

Edit vocabulary, add term, edit term still relevant. Couldn't figure out what "preview form" is referring to.

Moving to D8 and documentation.

These should not be in the documentation component, which is for API documentation. Trying to figure out where they should be:
#1195218: Need new component

It is a novice task tagging for core mentoring.

Added help text on the 'admin/structure/taxonomy/add' page.

Couldn't add help text for editing vocabularies for terms, because hook_help is implemented for the use of '%' as placeholder (see hook_menu() in D7), while in D8 the routing system is different.

Thanks for the patch... I am not the person who originally reported this issue, so I don't know what help they thought we needed on the taxonomy vocabulary add/edit forms. We don't have help on other add/edit forms, such as node/add forms, as far as I know. I think we should probably actually just skip this, especially since (as you noted) we cannot really do it for all the paths to be consistent.

I'm at the Drupal sprint in Austin taking a look at the Novice issues.

Maybe this isn't help text that's needed. . . on the node/add page the "help" that is being displayed is the description for the content type, i think. And the other 'help' on the following pages are descriptions for the fields.

I think we can use a tour instead of updating taxonomy_help for this change. Marking won't fix because it's marked "Postponed (maintainer needs more info)" for last year.

I'm cleaning up some Novice tag duplicates. removing the combined "novice documentation" tag so I can delete it, since we should be able to make a search for the novice tag combined with the documentation tag https://www.drupal.org/project/issues/search?projects=&project_issue_fol... or maybe even better: the documentation component combined with the novice tag https://www.drupal.org/project/issues/search/drupal?project_issue_follow...
