I haven't seen this.

What versions of ./scripts/get_maintainer.pl and git are
you using?

Jonathan is basically correct in the what he writes above.

I also think git history isn't a very good mechanism to
rely on for determining MAINTAINERS, it should only be a
fallback to determine who should receive a copy of a patch.

That said, I use scripts/get_maintainer.pl to generate
to's and cc's.  I do not use --git or --git-fallback
and rely only on the MAINTAINERS file pattern matching.

Here are the settings I use:

$ cat ~/.gitconfig
[sendemail]
	chainreplyto = false
	thread = false
	suppresscc = self
	tocmd = ~/bin/to.sh
	cccmd = ~/bin/cc.sh

$ cat ~/bin/to.sh
#!/bin/bash

opts="--nogit --nogit-fallback --norolestats --pattern-depth=1"

if [[ $(basename $1) =~ ^0000- ]] ; then
    ./scripts/get_maintainer.pl --nom $opts $(dirname $1)/*
else
    maint=$(./scripts/get_maintainer.pl --nol $opts $1)

    if [ "$maint" == "" ] ; then
	echo "linux-kernel@vger.kernel.org"
    else
	echo "$maint"
    fi
fi

$ cat ~/bin/cc.sh
#!/bin/bash

opts="--nogit --nogit-fallback --norolestats"

if [[ $(basename $1) =~ ^0000- ]] ; then
    ./scripts/get_maintainer.pl --nom $opts $(dirname $1)/*
else
    ./scripts/get_maintainer.pl $opts $1
fi
