Bug#869087: devscripts: [uscan] Files excluded without a matching pattern in debian/copyright's Files-Excluded

[Emmanuel Bourg]

Package: devscripts
Version: 2.17.9
Severity: normal

Hi,

While updating plexus-archiver I noticed that uscan filters more files
than expected.

The watch file is:

  version=3
  opts=uversionmangle=s{-alpha-}{~alpha} \
  https://github.com/codehaus-plexus/plexus-archiver/tags .*/plexus-archiver-(.*).tar.gz

The file downloaded is:

  https://github.com/codehaus-plexus/plexus-archiver/archive/plexus-archiver-3.5.tar.gz

And debian/copyright contains:

  Files-Excluded: jira

In this case the file plexus-archiver-plexus-archiver-3.5/src/test/resources/zeroFileMode/foobar.zip
and a few others are removed from the tarball. It doesn't happen
if the Files-Excluded field is removed.
