| 73 * text can be overwritten. | |
| 74 * Set: When any message is written to the screen. | |
| 75 * msg_nowait No extra delay for the last drawn message. | |
| 76 * Used in normal_cmd() before the mode message is drawn. | |
| 77 * emsg_on_display There was an error message recently. Indicates that there | |
| 78 * should be a delay before redrawing. | |
| 79 * msg_scroll The next message should not overwrite the current one. | |

| 91 * has answered some other prompt. | |
| 92 * Set: When the ruler or typeahead display is overwritten, | |
| 93 * scrolling the screen for some message. | |

| 272 | 4242 * This code was included to provide a portable vsnprintf() and snprintf(). |
| 715 | 4243 * Some systems may provide their own, but we always use this one for |
| 272 | 4244 * consistency. |
| 4245 * | |
| 4246 * This code is based on snprintf.c - a portable implementation of snprintf | |
| 4247 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06. | |
| 1189 | 4248 * Included with permission. It was heavily modified to fit in Vim. |
| 272 | 4249 * The original code, including useful comments, can be found here: |
| 4250 * http://www.ijs.si/software/snprintf/ | |
| 4251 * | |
| 4252 * This snprintf() only supports the following conversion specifiers: | |
| 4253 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below) | |
| 4254 * with flags: '-', '+', ' ', '0' and '#'. | |
| 4255 * An asterisk is supported for field width as well as precision. | |
