/**
 * Parse the footer lines (e.g. "Signed-off-by") for machine processing.
 * <p>
 * This method splits all of the footer lines out of the last paragraph of
 * the commit message, providing each line as a key-value pair, ordered by
 * the order of the line's appearance in the commit message itself.
 * <p>
 * A footer line's key must match the pattern {@code ^[A-Za-z0-9-]+:}, while
 * the value is free-form, but must not contain an LF. Very common keys seen
 * in the wild are:
 * <ul>
 * <li>{@code Signed-off-by} (agrees to Developer Certificate of Origin)
 * <li>{@code Acked-by} (thinks change looks sane in context)
 * <li>{@code Reported-by} (originally found the issue this change fixes)
 * <li>{@code Tested-by} (validated change fixes the issue for them)
 * <li>{@code CC}, {@code Cc} (copy on all email related to this change)
 * <li>{@code Bug} (link to project's bug tracking system)
 * </ul>
 *
 * @return ordered list of footer lines; empty list if no footers found.
