vi: code shrink search commands
Changes to search commands ('/', '?', 'n' and 'N'):
- Rewrite to be smaller and (possibly) clearer.
- Issue a warning when a repeat search is requested without a
previous search having been made.
Vim and BusyBox vi support a repetition count for searches though
the original vi doesn't. If the count exceeds the number of
occurrences of the search string the search may loop through the
file multiple times.
