In an indirect buffer `buffer-file-name' is nil, and consequently M-x
diff-buffer-with-file fails with "diff-no-select: Wrong type argument:
stringp, nil"
I think it would be sensible to use the base buffer's file name in this
situation.
Patch attached.

Looks reasonable. Can you push (to the master branch), or do you need
someone to do that for you? If the latter, please provide a commit
log message.
Thanks.
