11 | Bug-Description: | |
12 | ||
13 | In certain cases when outputting characters at the end of the line, | |
14 | e.g., when displaying the prompt string, readline positions the cursor | |
15 | incorrectly if the prompt string contains invisible characters and the | |
16 | text being drawn begins before the last invisible character in the line. | |
