[Dev-luatex] \shapemode does not reset at end of paragraphs

[Udicoudco]

The documentation states that \shapemode should reset to 0 at the end
of a paragraph if it is positive, but the following shows otherwise

\catcode`\{=1\catcode`\}=2
\directlua{tex.enableprimitives('',tex.extraprimitives ())}
\shapemode=1
\showthe\shapemode
\quitvmode\par
\showthe\shapemode
\end

I think the fix is a one liner.  I attached a patch.

Subject: [PATCH] fix reset of shape_mode

Consider the following example

\catcode`\{=1\catcode`\}=2
\directlua{tex.enableprimitives('',tex.extraprimitives ())}
\shapemode=1
\showthe\shapemode
\quitvmode\par
\showthe\shapemode
\end

shape_mode is of type int, not dimen
