Normalize content by removing all whitespace (spaces, tabs, newlines, carriage returns,
form feeds, and vertical tabs) and special characters.
NOTE: There are numerous unpredictable formatting oddities when transforming JavaScript to Markdown;
almost all of them are irrelevant to the actual content of the file, which is why we strip them out here.
For example:
In JavaScript, the following string table
| A | B | C |
| - | - | - |
| 1 | 3 | 5 |
| 2 | 4 | 6 |
| 3 | 5 | 7 |
| 4 | 6 | 8 |
| 5 | 7 | 9 |
parses to Markdown as
| A | B | C |
| --- | --- | --- | <--------- notice the extra hyphens
| 1 | 3 | 5 | <--------- notice the extra spaces
| 2 | 4 | 6 |
| 3 | 5 | 7 |
| 4 | 6 | 8 |
| 5 | 7 | 9 |
This is one of many arbitrary formatting anomalies that we can ignore by normalizing the
content before comparing the JavaScript template literals and the final Markdown.
