dpkg-source: -I implicitly used for 3.0 quilt format

[Jason Abernathy]

When building source packages (format 3.0 - quilt) with the dpkg-source command, the -I seems to be implicitly used when it isn't specified on the command line.

I've attached a small debian package named foo-app which demonstrates this behaviour.

I've added three binary files (named extra/bar, extra/bar.so and extra/bar.a) to foo-app
> tar -xzf foo-app-full.tgz
> cd fooapp-1.0

According to the man page for dpkg-source, unexpected binaries will cause the build to fail, "unless the maintainer deliberately decided to include that modified binary file in the debian tarball (by listing it in debian/source/include-binaries)". The files are listed correctly.

> cat debian/source/include-binaries
extra/bar
extra/bar.so
extra/bar.a

Building the source package without specifying any value for the -I parameter will result in the "extra/bar" file being included in ../fooapp_1.0-1.debian.tar.gz, but not the other two binaries.

> dpkg-source -b .
dpkg-source: info: using source format `3.0 (quilt)'
dpkg-source: info: building fooapp using existing ./fooapp_1.0.orig.tar.gz
dpkg-source: info: building fooapp in fooapp_1.0-1.debian.tar.gz
dpkg-source: info: building fooapp in fooapp_1.0-1.dsc

> tar -ztf ../fooapp_1.0-1.debian.tar.gz | grep bar
extra/bar

When the source package is built with a dummy value for the -I parameter, all three files are included in ../fooapp_1.0-1.debian.tar.gz.

> dpkg-source -b -I*.dat .
dpkg-source: info: using source format `3.0 (quilt)'
dpkg-source: info: building fooapp using existing ./fooapp_1.0.orig.tar.gz
dpkg-source: info: building fooapp in fooapp_1.0-1.debian.tar.gz
dpkg-source: info: building fooapp in fooapp_1.0-1.dsc

> tar -ztf ../fooapp_1.0-1.debian.tar.gz | grep bar
extra/bar.so
extra/bar.a
extra/bar

This leads me to believe that -I is being used by default. If this is intentional, then the man page for dpkg-source should be updated so that the requirements for including a binary with the 3.0 quilt format include overriding the -I parameter.
