| 49 * lowest: searchit(); uses an pos_T for starting position and found match. | |
| 50 * Highest: do_search(); uses curwin->w_cursor; calls searchit(). | |
| 51 * | |
| 52 * The last search pattern is remembered for repeating the same search. | |
| 53 * This pattern is shared between the :g, :s, ? and / commands. | |
| 54 * This is in search_regcomp(). | |
| 55 * | |
| 56 * The actual string matching is done using a heavily modified version of | |
| 57 * Henry Spencer's regular expression library. See regexp.c. | |
