Lintian tag information: dfsg-version-with-period (type: information)

Description (from lintian-explain-tags)

The version contains the string .dfsg. That versioning may harbor a subtle
sorting issue, namely: 1.2.dfsg1 is a more recent version than 1.2.1. It
will therefore be difficult to find a nice version string for the next
upstream release if it gains another dotted digit at the end.

It is better to use +dfsg instead. The plus sign + sorts before ., so the
sorting that is usually desired can take place:

1.2 < 1.2+dfsg < 1.2.1
