| 68 * Set: When any message is written to the screen. | |
| 69 * msg_nowait No extra delay for the last drawn message. | |
| 70 * Used in normal_cmd() before the mode message is drawn. | |
| 71 * emsg_on_display There was an error message recently. Indicates that there | |
| 72 * should be a delay before redrawing. | |
| 73 * msg_scroll The next message should not overwrite the current one. | |

| 75 * messages). Used in update_screen() to scroll the screen | |

| 85 * has answered some other prompt. | |
| 86 * Set: When the ruler or typeahead display is overwritten, | |
| 87 * scrolling the screen for some message. | |

| 272 | 4236 * consistency. |
| 4237 * | |
| 4238 * This code is based on snprintf.c - a portable implementation of snprintf | |
| 4239 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06. | |
| 1189 | 4240 * Included with permission. It was heavily modified to fit in Vim. |
| 272 | 4241 * The original code, including useful comments, can be found here: |
| 4242 * http://www.ijs.si/software/snprintf/ | |
| 4243 * | |
| 4244 * This snprintf() only supports the following conversion specifiers: | |
| 4245 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below) | |
| 4246 * with flags: '-', '+', ' ', '0' and '#'. | |
