annotate src/getchar.c @ 3231:910eb66c9768 v7.3.385
updated for version 7.3.385
Problem: When using an expression mapping on the command line the cursor
ends up in the wrong place. (Yasuhiro Matsumoto)
Solution: Save and restore msg_col and msg_row when evaluating the
expression.

| 22 * These buffers are used for storing: | |
| 23 * - stuffed characters: A command that is translated into another command. | |
| 24 * - redo characters: will redo the last change. | |
| 1992 | 25 * - recorded characters: for the "q" command. |
| 7 | 26 * |
| 27 * The bytes are stored like in the typeahead buffer: | |
| 28 * - K_SPECIAL introduces a special key (two more bytes follow). A literal | |
| 29 * K_SPECIAL is stored as K_SPECIAL KS_SPECIAL KE_FILLER. | |
| 30 * - CSI introduces a GUI termcap code (also when gui.in_use is FALSE, | |
| 31 * otherwise switching the GUI on would make mappings invalid). | |
| 32 * A literal CSI is stored as CSI KS_EXTRA KE_CSI. | |
| 33 * These translations are also done on multi-byte characters! | |
| 34 * | |
| 35 * Escaping CSI bytes is done by the system-specific input functions, called | |
| 36 * by ui_inchar(). | |
| 37 * Escaping K_SPECIAL is done by inchar(). | |
| 38 * Un-escaping is done by vgetc(). | |
