search: remember last searched-for string between searches

Browse source 
Regardless of how we exit search mode (commit or cancel), the search
string is remembered.

The next time we enter search mode, the last searched-for string will
be used when searching for the next/prev match (ctrl+r, ctrl+s), and
the search query is empty.
