Checking now the new warning, it might also make sense to print the
package involved from DPKG_MAINTSCRIPT_PACKAGE so the message is more
clear.

Ok.

Given the size of the transition this is going to be a small pain
compared to the total, but yes, you are right, I guess it makes more
sense.

I was going to give some comments, but then I thought it was going to
be easier with code, so here it is
<http://git.hadrons.org/?p=debian/dpkg/dpkg.git;a=shortlog;h=pu/install-info>
this way it might be possible to reuse this as the wrapper for the
install-info package.
