Thanks for the detective work, Peter and drkm.

As far as I understand it, the reason for using the temp buffer is: If
an error occurs while publishing, don't clobber the original file.

Unfortunately, passing `t' as the second argument to
`insert-file-contents' seems to defeat this purpose.  It isn't
desirable to still have the file associated with the temp buffer.  My
guess is that once this command is modified (dropping the second
argument), the problem with the buffer-clobbering will be gone.

I think I'll try to modify (and rename!)
`muse-with-temp-buffer-no-prompt' so that it pops up a window with
information when an error occurs.  I'm not sure if the temp buffer
should be kept around ... maybe I'll make a debugging option that will
determine whether or not to kill the buffer.
