I've submitted this first to this list as a feature request, however in the meantime with the help of Jeff King <peff@peff.net>, Junio C Hamano <gitster@pobox.com>, Eric Sunshine <sunshine@sunshineco.com> and Mikael Magnusson <mikachu@gmail.com> came up with solution, so now I submit it as a revised patch.
The current solution updates the progress for all commits until 1 second time is elapsed. Afterwards updates it at most once a second. --- git-filter-branch.sh | 42 +++++++++++++++++++++++++++++++++++++++++- 1 file changed, 41 insertions(+), 1 deletion(-)
