Bug-Description:
|
|
Roman Rakus |
3a5a59 |
|
|
Roman Rakus |
3a5a59 |
An off-by-one error caused the shell to skip over CTLNUL characters,
|
|
Roman Rakus |
3a5a59 |
which are used internally to mark quoted null strings. The effect
|
|
Roman Rakus |
3a5a59 |
was to have stray 0x7f characters left after expanding words like
|
|
Roman Rakus |
3a5a59 |
""""""""aa.
