Summary: vi on busybox 1.12.1 has a null pointer dereference
Description:
last_search_pattern in vi.c doesn't get initialized to anything, yet the
code under FEATURE_VI_SEARCH attempts to use it without checking.
Simply starting vi and hitting 'N' can trigger it. Also, doing an empty
search (newline only) also triggers it.
If I set last_search_pattern to "" in main, it fixes it. I'm not sure if
that's an appropriate fix though.
