Bug-Description:
|
||
|
|
|
||
|
|
Bash-4.4 warns when discarding NUL bytes in command substitution output
|
||
|
|
instead of silently dropping them. This patch changes the warnings from
|
||
|
|
one per NUL byte encountered to one warning per command substitution.
|
||
|
|
|
||
|
|
Patch (apply with `patch -p0'):
