Is there any way to get emacs to actually check the contents of files on disk when determining this?

E.g. if I have some unsaved changes to a file, and temporarily switch source control branches (to make changes to other files), then switch back again, I want to be able to continue editing where I left off without this prompt. (the prompt would be much more trustworthy and useful if it only warned me when the file had really changed)

I think it currently goes by timestamp or something.

  • Thanks @lawlist, read that prior to posting. I don't want to ignore it when the files have actually changed. – EoghanM Apr 13 '15 at 09:50

  • I agree @EoghanM that this is a separate question, but might be worth resubmitting the question on http://emacs.stackexchange.com/ . I'd be interested in any answer. – Rich Smith Mar 18 '16 at 11:02
