Subject: [PATCH] Bug 706778: 706761 revisit
|
|
|
|
Two problems with the original commit. The first a silly typo inverting the
|
|
logic of a test.
|
|
|
|
The second was forgetting that we actually actually validate two candidate
|
|
strings for pipe devices. One with the expected "%pipe%" prefix, the other
|
|
using the pipe character prefix: "|".
|
|
|
|
This addresses both those.
