The reason for putting them in doc turned out to be misguided

Simply use top-level functions + a plain object.

Detect when new position falls outside of a line, and retry. Also
replaces the kludgy widget compensation code.

Multi-line Lua comments start with "--[[", not "--["

Issue #881

By growing the vertical scrollbar to cover the whole editor when a wheel scroll
is taking place.

(This to avoid manually handling wheel events, for which there doesn't appear
to be any way that feels native across browsers.)

Closes #810

And add marker changes to the undo history, so that
un/redoing doesn't cause 'ghost' markers to appear.

Closes #882

So that, even though they share a z-index, they overlay the text and
marked spans.

Closes #875

Closes #857

There are cases when widget could be a different repsentation of code, so while folding the code 
one may want to show widgets for hidden lines.

I added showWidgets parameter to foldLines, if set it allows widgets for hidden lines to be shown.
Here is a simple showcase where this functionality is needed:

To turn off the behavior where it'll always complete when only
a single option is left.

Closes #868

I tend to have some variety of it sitting in the root dir.

- Add options to Markdown mode to make it easier to extend
- Add GFM text overlay
  - SHA, User@SHA, and User/Project@SHA
  - #Num, User/#Num, and User/Project#Num
  - Vanilla URLs
- Add GFM-specific tests
- Fix overlay code so blankLine() is called
- Fix GFM for v3

- Inline links (square brackets followed by parentheses) cannot be separated by space (per Documentation and Dingus).

- Added test that checks both for this and correct highlighting of square brackets by themselves.

Also avoid a global variable that snuck through.

To make it easier for themes to override it.

Fixes ambiance
