| 5782 * Match a regexp against multiple lines. | |
| 5783 * "rmp->regprog" is a compiled regexp as returned by vim_regcomp(). | |
| 5784 * Uses curbuf for line count and 'iskeyword'. | |
| 5785 * | |
| 5786 * Return zero if there is no match. Return number of lines contained in the | |
| 5787 * match otherwise. | |
| 5788 * | |
| 5789 * Note: the body is the same as bt_regexec() except for nfa_regexec_both() | |
| 5790 * | |
| 5791 * ! Also NOTE : match may actually be in another line. e.g.: | |
| 5792 * when r.e. is \nc, cursor is at 'a' and the text buffer looks like | |
| 5793 * | |
| 5794 * +-------------------------+ | |
| 5795 * |a | | |
| 5796 * |b | | |
| 5797 * |c | | |
| 5798 * | | | |
| 5799 * +-------------------------+ | |
| 5800 * | |
| 5801 * then nfa_regexec_multi() returns 3. while the original | |
| 5802 * vim_regexec_multi() returns 0 and a second call at line 2 will return 2. | |
