| 75 * msg_nowait No extra delay for the last drawn message. | |

| 272 | 4120 * This code was included to provide a portable vsnprintf() and snprintf(). |
| 715 | 4121 * Some systems may provide their own, but we always use this one for |
| 272 | 4122 * consistency. |
| 4123 * | |
| 4124 * This code is based on snprintf.c - a portable implementation of snprintf | |
| 4125 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06. | |
| 1189 | 4126 * Included with permission. It was heavily modified to fit in Vim. |
| 272 | 4127 * The original code, including useful comments, can be found here: |
| 4128 * http://www.ijs.si/software/snprintf/ | |
| 4129 * | |
| 4130 * This snprintf() only supports the following conversion specifiers: | |
| 4131 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below) | |
| 4132 * with flags: '-', '+', ' ', '0' and '#'. | |
| 4133 * An asterisk is supported for field width as well as precision. | |
