I recall that Microsoft Word stored previous edits of the document
within the document. One day an irate employee wrote a letter to the
boss and started it with "Dear <expletive deleted>," but before
e-mailing the letter changed it to Dear Mr. <Name>. Unfortunately, the
boss opened the letter in a different program and could see all the
edits. This did not go well for Microsoft.
