Subject: [PATCH] [ng] texi: move some more knowledge from automake to
 texi-spec.am

* automake.in (handle_texinfo_source): Do not define '$dipfx',
nor use it for the transform '%DEST_INFO_PREFIX%'.
* lib/am/texi-spec.am: Adjust the prefix of the output info file
by adding '$(srcdir)' to it if the '?INSRC?' transform is true.
