[Bug 1616953] [NEW] dpkg --compare-versions comparison incorrect for some package versions

[Christopher Townsend]

Public bug reported:

I have a situation where dpkg --compare-versions is reporting the wrong
status for certain package versions.

A simple example:

$ dpkg --compare-versions 1.3.1+16-0ubuntu1-0 gt 1.3.1-0ubuntu1-0
$ echo $?
1

It is the second '-' in the second version that is triggering this.  The
first version should be greater than the second.

I spoke w/ Ken VanDine about this and he agreed that this looks like a
big.
