Fixes#2705.
Fixes#7635.
This PR fixes the commit graph showing false connections for orphan/root commits. Connection lines are now shown only when a parent/child relationship exists. Visible relationships are determined using `git log`'s `%P` output by the new `ComputeGlyphConnectivity` function. The SVG template is adapted to render vertical lines conditionally.
Unit tests for `ComputeGlyphConnectivity` cover regular linear commit history, orphan commits, merge commits, and non-commit glyphs (`|`, `/`, `\`). Unit tests also cover the changes to the `git log` parsing. The SVG template was verified manually.
