bug#11238: 24.0.95; eval-buffer and load hangup problem

From: Atsuo Ohki
Subject: bug#11238: 24.0.95; eval-buffer and load hangup problem
Date: Fri, 13 Apr 2012 17:09:12 +0900

A file, which has illformed file local variable specification
like "; -*-", makes eval-buffer and load functions hangup.

an exit condition of lisp_file_lexically_bound_p(src/lread.c) is
not enough.
