In order to make a commit be invariant (excluding ID) over a format-patch and subsequent am cycle, one needs to use the '--keep-non-patch' so that commits like:
[PATCH] [i386] fix foo bar arch/x86/mm
only lose the [PATCH] and not the [i386] part. Since it is a common desire (e.g. linux kernel stable trees) to have the subjects remain invariant during a backport, there is a genuine need for making this the default behaviour from a config file, versus specifying it in scripts and on the command line each time.
