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