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.

+ Normally git-mailinfo strips from the Subject line, all leading
+ strings bracketed with [ and ] pairs. If this setting is true,
