| 1916 * This is used for abbreviated commands like "D" -> "d$". | |
| 1917 * Also used to redo a command for ".". | |

| 1919 * Stores text obtained previously but not used yet. | |
| 1920 * Also stores the result of mappings. | |

| 1923 * This may do a blocking wait if "advance" is TRUE. | |
| 1924 * | |
| 1925 * if "advance" is TRUE (vgetc()): | |

| 4389 * characters or all non-id characters. This allows for abbr. "#i" to | |

| 4391 * | |
| 4392 * Vim addition: Allow for abbreviations that end in a non-keyword character. | |
