Changes:
 apt (2.9.18) unstable; urgency=medium
 .
   * Fix out-of-bounds read in `apt show :` (Closes: #1090068)
   * Introduce git-like automatic pager for apt(8), emulating git behavior.
     It is enabled for the show, list, search, policy, showsrc commands.
     The pager can be set using APT_PAGER or PAGER and defaults to `pager`
   * Add initial pinning information to apt show --full.
     The fields `APT-Pin`, `APT-Candidate`, and `APT-Release` provide
     pinning information. It is not yet possible to see multiple sources,
     and the per-source pinning is not shown.
   * gpgv: Extract VerifyDetachedSignatureFile()
