Bug in M4

[Sam Lauber]

I am using M4 1.4.2.
I wrote an example of m4wrap which did the following:

define macros
initalize by m4wrapping to an action to remove a temp file

However, I ran m4 -R on it, and it said

(my initalizing message)
(my cleaning-up message)

I expected

(my initalizing message)

I ran m4 -F on the generated file, and pressed EOF. I got
nothing. I expected

(my cleaning-up message)

This seriously reduces the usefulness of m4wrap, since large
applications have to establish cleanup actions, and large
applications typically are in frozen files.
My input file was attached.
