Andrew Borodin 5ffcffbeb6 Optimization of history saving.
Now history is not saved if it was not modified and content of input
line is equal to history top entry. Thanks Francesco Cosoleto
<cosoleto at gmail dot com> for the original patch.

Also fixed a regression introduced in cff59255982d470b11a97408d7d3571b03b8401a:
after CK_HistoryNext and CK_HistoryPrev actions in input line,
the input line content is not put to the top of history.
