Incremental search does not remember old search string

[guth]

In GNU Emacs emulation, Ctrl-s starts incremental search. If the search is interrupted, then one can get back to the old search string by pressing Ctrl-s Ctrl-s. This does not work anymore. When doing this, I get the current word under the cursors.

Thanks for the report.  I am able to reproduce this one, it looks like you have the option enabled to initialize search string to Word at Cursor.  It shouldn't use that setting for incremental search, I will try to get that corrected.
