Bug#827065: /usr/bin/uscan: [uscan] please extend git tag support for signed git tag with pgpmode

[Neil Williams]

Package: devscripts
Version: 2.16.5
Severity: wishlist
File: /usr/bin/uscan

uscan supports git tags in the debian/watch file but lintian picks up that
the signatures could be checked. uscan seems to lack this support - assuming
that a separate .asc or .sig file can be downloaded which does not work for
a signed git tag.

(If I've missed how to do this, please add an example to the manpage for uscan.)
