gitconfig parser fails to parse config keys without values

[auscompgeek]

Here is a snippet of my ~/.config/git/config:

[diff]
    mnemonicPrefix
[rebase]
    stat
[merge]
    summary
    tool = vimdiff

GitPython raises a configparser.ParsingError for the lines without values:

Traceback (most recent call last):
