Bug-Description: |
|
|
|
When used in contexts where word splitting and quote removal were not |
|
performed, such as pattern removal or pattern substitution, empty strings |
|
(either literal or resulting from quoted variables that were unset or |
|
null) were not matched correctly, resulting in failure. |
|
|
|
Patch (apply with `patch -p0'): |
