Thank you, I just learned a new cool tool!
FWIW, here's what I used successfully on a repository with only one
ChangeLog file (some fiddling to cope with format variations):
git filter-branch -d /dev/shm/t --tree-filter '
line=`sed -n "s,^[12][90][0-9][0-9]-[0-1][0-9]-[0-3][0-9] *\([A-Za-z].*\),\1,;
s,.* \([A-Za-z].*\),\1,;
/./{
s/(tiny change)//
s/ *$//
p
q
}" ChangeLog`
author=`echo "$line" | sed "s, *[<(].*,,"`
email=`echo "$line" | sed "s,[^,(]*[<(],<,; s/[)>].*/>/"`
test -n "$author" && test -n "$email" && {
GIT_AUTHOR_NAME="$author"
GIT_AUTHOR_EMAIL="$email"
export GIT_AUTHOR_NAME GIT_AUTHOR_EMAIL
}'

I'll try that, too.
Thanks!
