When the option `log.show-signature` is set in `.gitconfig` the parser does not work: ``` > git-who --version v0.6 5249eb5 > git-who [works fine] > git config --global log.show-signature true > git-who error running "table": failed to tally commits: error iterating commits: error parsing date from commit gpg: Signature made 2020-05-12T12:47:56 UTC: strconv.Atoi: parsing "a67ca69": invalid syntax ``` Probably `.gitconfig` [should be ignored](https://superuser.com/a/1255922)
