 - Option `gitCommitCountLimit` is a maximum number of commits to search for when doing rev walk on git push hook - used just on the user side while running commands `--verify-unpushed-commits` or `--skip`. It this number is reached you'll get a warning and ignoring it may result in some files being ommited from tag verification.
