Comment 7 for bug 595186

Revision 1397 of the honly2 branch implements a first solution to this issue.

The variable `vm-external-fetch-message-for-presentation' can be set to `nil' to disable automatic fetching for the viewing of messages. Message bodies can only be loaded using the `o' command (which loads rather than fetches).

It would be better to use <SPC> (vm-scroll-forward) to do fetching. But we are not there yet.
