*** 1. prepare objects (munge, sanitize, markup)
**** 1. _text_ generic munge (sanitize text for search)

- [3/4] (search text, applies to all but code blocks)
  - [ ] remove whitespace, paragraph on single line (formatting kept so far)
  - [X] remove font face attributes
  - [X] move embedded endnotes
    - [X] place after text object
    - [X] remove embedded endnote numbers (rely on html output to represent)
  - [X] urls
    - [X] clean url markers, leave plain link text
    - [X] place urls after text object and its endnotes
