Ah, good catch, I will keep an eye on it before uploading.

Patch forwarded upstream:

As I wrote there, after having found where the bug originated:

  However, the readline support is never available if you do not have
  TERM_LIB because of [4], which basically put conio and readline at the
  same level in terms of dependencies. I was not able to find any reason
  for this change in the ChangeLog neither in the BTS and similar bugs
  were either too old (0000743 [5]) or not related (0001226 [6]).

  dpkg-shlibdeps still complains about unused symbols, but this time
  only for libhistory.so.6:
