The documentation does not require "saving the file from its buffer",
but mentions "saving the file from a buffer", and save-buffer is
described as "Save current buffer in visited file". If save-buffer does
not qualify as saving a file from a buffer, then indeed please consider
the issue addressed. Thank you a lot!
