*tex-shell* is read only

[Joe Corneli]

In the latest version of CVS emacs, one can't process tex files with
the command `tex-buffer' by default, since the buffer *tex-shell* is
read only.

With -q --no-site-file command line options, issuing C-c C-b in a
sample TeX file gave these messages, but didn't do anything else:
