@includeverbatim causes spurious empty lines in Info and HTML

I have a big document which includes bits from files generated from
the document itself.  For instance, for something like:

    But the game becomes more interesting when you implement function calls
    (which is much more easy than compiling functions).
    
    @example
    (print_int (101); print ("\n"))
    @end example
    @filecaption{21, print-101.tig}
    @tccaption{22, --hir-display print-101.tig > print-101.hir}
    @havmcaption{23, print-101.hir}

The script sees the address@hidden, print-101.tig}', hence stores
the contents of the @example into the file `print-101.tig', and then
runs `tc --hir-display print-101.tig > print-101.hir', and finally
runs `havm print-101.hir' and stores the result in the file named
`23'.

Finally, macros such as @tccaption and @havmcaption are defined as:


    @c tccaption(ORDINAL, TC-ARGUMENTS)
    @c ================================
    @macro tccaption{ordinal, args}
    @example
    $ @kbd{tc \args\}
    @include extract/\ordinal\
    @end example
    @noindent @strong{Example \ordinal\}: @i{tc \args\}
    @end macro

It works great.  My document is really maximally generated, which is
important to keep up to date information.  You may have a look at
http://www.lrde.epita.fr/~akim/compil/reports.html for more.


Now my problem is that some section are truly ugly because of spurious
empty lines.  It basically amounts to:

Attachment: foo.texi
Description: TeXInfo document

with the file `foo' containing a single line containing `foo'.

It results in:

/tmp % makeinfo --no-headers foo.texi
Before

     BEFORE
                                       <= gross
     foo
     AFTER

after.

/tmp %

texi2dvi produces exactly what I expect:

   Before

     BEFORE
     foo
     AFTER

after.

and html is the worst of all:

/tmp % makeinfo --html foo.texi -o-                              nostromo 17:13
<html lang="en">
<head>
<title>Sans titre</title>
<meta http-equiv="Content-Type" content="text/html">
<meta name=description content="Sans titre">
<meta name=generator content="makeinfo 4.2">
<link href="http://www.gnu.org/software/texinfo/"; rel=generator-home>
</head>
<body>
Before

<br><pre>BEFORE

<pre>foo
</pre>AFTER
</pre>

<p>after.

</body></html>

/tmp % links -dump =(makeinfo --html foo.texi -o-)
   Link: generator-home
   Before

 BEFORE


 foo

 AFTER

   after.
/tmp %

The empty lines all around `foo' are really wrong IMHO.

I have seen activity around the HTML output lately, maybe it is
already fixed somewhere?

It really ought to be equivalent to inlining the foo file, i.e.,

/tmp % cat foo.texi
\input texinfo


Before

@example
BEFORE
foo
AFTER
@end example

@noindent
after.

@bye
/tmp % links -dump =(makeinfo --html foo.texi -o-)
   Link: generator-home
   Before

 BEFORE
 foo
 AFTER

   after.
/tmp %


Thanks!
