Get rid of a rescue nil
Get rid of a rescue nil

From the commit (cfdf97d4) which introduced it:

-        begin
-          data = ::IO.read(file).split(/^__END__$/)[1]
-        rescue
-          data = nil
-        end
+        app, data =
+          ::IO.read(file).split(/^__END__$/, 2) rescue nil

The rescue block in the cfdf97d4^ tree was introduced in b88c0f5
because of #201. I am not 100% sure that rescueing Errno::ENOENT
is enough, though. Please let me know if it is not.
