34 * 1. string searches (for /, ?, n, and N)

40 * String searches
41 *
42 * The string search functions are divided into two levels:
43 * lowest: searchit(); uses an pos_T for starting position and found match.
44 * Highest: do_search(); uses curwin->w_cursor; calls searchit().
45 *
46 * The last search pattern is remembered for repeating the same search.
47 * This pattern is shared between the :g, :s, ? and / commands.
48 * This is in search_regcomp().
49 *
50 * The actual string matching is done using a heavily modified version of
51 * Henry Spencer's regular expression library. See regexp.c.
