Prior to this commit, git commands (such as the command to get
remote.origin.url
) would always be run if git was installed. This caused "fatal: not a git repository" to be printed tostderr
when the project was not a git repository.This commit modifies
SDoc::Helpers::Git#git?
such that git commands will only be run if git is installed and the project is a git repository.
