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