Signed commits break building and installing from git repo if log.showSignature=true in git

[AdrianVollmer]

You recently started to sign commits, which is great. However, it breaks constructing the version number in setup.py. When someone has set log.showSignature=true in git, building and installing impacket from sources fails.

Configuration

impacket version: 15eff88
Python version: 3.7.3 (but affects all)
Target OS: Debian Sid

Debug Output With Command String

$ git clone https://github.com/fortra/impacket.git
$ cd impacket
$ python3 setup.py --version

Additional context

If you're parsing git output, you should use the last line. An even better solution would be to use a modern build system such as hatch.
