Documentation

Function to get the region's content.

Called with one argument METHOD which can be:
- nil: return the content as a string (list of strings for
  non-contiguous regions).
- delete-only: delete the region; the return value is undefined.
- bounds: return the boundaries of the region as a list of one
  or more cons cells of the form (START . END).
- anything else: delete the region and return its content
  as a string (or list of strings for non-contiguous regions),
  after filtering it with filter-buffer-substring, which
  is called, for each contiguous sub-region, with METHOD as its
  3rd argument.
