I studied the existing Org handling of various errors related to src
edit buffers and it seems that we tend to ignore them in a number of
scenarios. In particular, when major mode fails to load for any reason,
Org mode does not even throw an error, but simply displays a warning.

So, I think that we can similarly ignore errors in edit-prep function,
demoting them to messages.

(In addition, it does not look like electric-indent-mode triggered in
your example file by pressing <RET> handles errors gracefully either -
yet another reason not to throw errors in `org-indent-*' functions)

Does it make sense?
