Subject: ui-commit: handle root commits
X-Git-Url: https://gitweb.ps.run/ps-cgit/commitdiff_plain/502d57596e645ec91bb9b8ca62833cdb0de4a3b1?hp=502d57596e645ec91bb9b8ca62833cdb0de4a3b1

ui-commit: handle root commits

Both cgit_print_diff() and cgit_diff_tree() handles root commits nicely,
but cgit_print_commit() forgot to check the case of 0 parents.

This fixes it, and adds tests to avoid future regressions.
