vi: stored search pattern applies to ':s'

Browse Source 
The same stored search pattern applies to both search ('/') and
search/replace (':s') operations.

A search/replace operation with an empty "find" string (':s//abc/')
should use the last stored search pattern, if available, and issue an
error message if there is none.

If the "find" string is not empty it should replace the stored search
pattern.
