Initialize the search buffer.

Otherwise, if you called ed-search-prev-history before doing any
history search but after entering at least one line into the history,
the buffer could get accessed uninitialized, potentially resulting
in a read buffer overrun.

Segfault reported in sftp(1) via djm@ by Alf Schlichting <A dot
Schlichting at lemarit dot com>, who also confirmed that the patch
fixes the issue for him.
