Optimization of history saving.

Browse Source 
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 cff5925598:
after CK_HistoryNext and CK_HistoryPrev actions in input line,
the input line content is not put to the top of history.
