Bug-Description:
|
|
|
ff19ae |
|
|
|
ff19ae |
Process substitution incorrectly inherited a flag that inhibited using the
|
|
|
ff19ae |
(local) temporary environment for variable lookups if it was providing
|
|
|
ff19ae |
the filename to a redirection. The intent the flag is to enforce the
|
|
|
ff19ae |
Posix command expansion ordering rules.
