Thank you, that will do very nicely as a starting point.

What I _really_ want is the subset of all commits containing foo
who's oneline commit message doesn't match a given regexp.

So I'm used something like this to extract the commits of interest:

git log -z -p | perl -0ne 'print if /^[-+].*foo/m' | tr '\0' '\n' |
grep "^commit [0-9a-f]" | awk '{print $2}' |
xargs -n1 git log --pretty=oneline -1 |
grep -v dont_want

In this specific case of wanting to ignore particular commits a loop
over git-rev-list might yield a better solution.  But the 'git-log | perl | tr'
snippet is a nice idiom for day-to-day use.
