Possibly, but the flag is called --invert-grep not --invert-matches so
one would expect it to revert grep only. Though behaviour contrary to
user expectations is not an unusual property of git :)

Other than piping to e.g. awk or worse, how would one get the commits
by a particular author that do not have a specific string in the
commit message? Prettying to oneline would make the piping easier to
at least get the commit ids, but I'd like to see the whole commit
message and affected files.

Thanks, Junio.
