11 Bug-Description: |
|
12 |
|
13 Process substitution incorrectly inherited a flag that inhibited using the |
|
14 (local) temporary environment for variable lookups if it was providing |
|
15 the filename to a redirection. The intent the flag is to enforce the |
|
16 Posix command expansion ordering rules. |
