[PATCH v2 2/2] commit-graph.txt: improve formatting for asciidoc

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <dstolee@microsoft.com>

When viewing commit-graph.txt as a plain-text document, it makes
sense to keep paragraphs left-padded between bullet points.
However, asciidoc converts these left-padded paragraphs as monospace
fonts, creating an unpleasant document. Remove the padding.

The "Future Work" section includes a bulleted list of items, and one
item has sub-items. These do not render properly in asciidoc, so
remove the sub-list and incorporate them into the paragraph.

 This property can be used to significantly reduce the time it takes to
 walk commits and determine topological relationships. Without generation
 numbers, the general heuristic is the following:
 
-    If A and B are commits with commit time X and Y, respectively, and
-    X < Y, then A _probably_ cannot reach B.
