| 64 * Reset: After hitting a key for the hit-return prompt, | |

| 67 * msg_didout TRUE when something was written to the current line. | |
| 68 * Reset: When advancing to the next line, when the current | |
| 69 * text can be overwritten. | |
| 70 * Set: When any message is written to the screen. | |
| 71 * msg_nowait No extra delay for the last drawn message. | |
| 72 * Used in normal_cmd() before the mode message is drawn. | |
| 73 * emsg_on_display There was an error message recently. Indicates that there | |
| 74 * should be a delay before redrawing. | |
| 75 * msg_scroll The next message should not overwrite the current one. | |
| 76 * msg_scrolled How many lines the screen has been scrolled (because of | |
| 77 * messages). Used in update_screen() to scroll the screen | |
| 78 * back. Incremented each time the screen scrolls a line. | |

| 83 * lines_left Number of lines available for messages before the | |
| 3240 | 84 * more-prompt is to be given. -1 when not set. |
| 7 | 85 * need_wait_return TRUE when the hit-return prompt is needed. |
| 86 * Reset: After giving the hit-return prompt, when the user | |
| 87 * has answered some other prompt. | |
| 88 * Set: When the ruler or typeahead display is overwritten, | |
| 89 * scrolling the screen for some message. | |
| 90 * keep_msg Message to be displayed after redrawing the screen, in | |
| 91 * main_loop(). | |

| 272 | 4101 * This code was included to provide a portable vsnprintf() and snprintf(). |
| 715 | 4102 * Some systems may provide their own, but we always use this one for |
| 272 | 4103 * consistency. |
| 4104 * | |
| 4105 * This code is based on snprintf.c - a portable implementation of snprintf | |
| 4106 * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06. | |
| 1189 | 4107 * Included with permission. It was heavily modified to fit in Vim. |
| 272 | 4108 * The original code, including useful comments, can be found here: |
| 4109 * http://www.ijs.si/software/snprintf/ | |
| 4110 * | |
| 4111 * This snprintf() only supports the following conversion specifiers: | |
| 4112 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below) | |
| 4113 * with flags: '-', '+', ' ', '0' and '#'. | |
| 4114 * An asterisk is supported for field width as well as precision. | |
