patch to textmodes/tex-mode.el for tex-view

[David Casperson]

(Note:  this bug is independent of most of the following attached
information.  It dates back several versions of emacs.)

The symptoms are.  M-x tex-view fails if the *tex-shell*
process is not alive (perhaps because the user killed the *tex-shell*
buffer, perhaps because the user is trying to run tex-view after
restarting emacs itself before running tex-file).

The following patch to lisp/textmodes/tex-mode.el (pardon the
re-naming in the diff) cures this.

--- tex-fix-view.el     Tue Mar 15 10:33:30 2005
