I understand.

Before I give thought to reworking the change, perhaps some other
considerations.


The other interesting thing is that Alan brought up the relevant point
about stuff breaking.

What are your thoughts regarding the introduction of cn_escape() in this patch ?

https://lkml.org/lkml/2011/6/7/292


While this change also has merit, it is also breaking change. There might
be code relying on %e containing embedded slashes, either directly in
core pattern:

%e.core

or via the pipe:

| /opt/corehandler '%e'



Isn't the interface change introduced by cn_escape() also a concern ?
