Re: normal-mode breaks VM recover-file

[Richard M. Stallman]

    With latest CVS emasc I upgraded to last week, I found that VM would
    no longer be able to "recover-file" from an auto-saved copy
    properly. After further investigation, VM would not proceed with
    recovering because the major mode (VM mode) was reset to text-mode
    during the recovery in normal-mode (in files.el). 

I don't remember which bug this fixed, but I am sure it was a bug.
Perhaps the bug was that if you delete the -*- line from a file and do
M-x normal-mode, it would fail to switch to Fundamental mode.

Why does Emacs think that Text mode is the right mode?  Can you set it
up to recognize automatically that VM mode is the right mode for these
files?
