File names have two small errors.

[johanley]

The file names are long-winded as a convenience: different contexts identify the chapters in different ways.
There are two small errors in the file names:

• Chapter 35: the dot is missing after XXXV
• Chapter 30: the apostrophe is a vertical apostrophe.

These small errors will likely never be corrected. Note that the "true" chapter title is defined by the file's first line, not by the file name.
