I had to squint a bit to see what you were getting at here, which is
pretty simple: When you provide --invert-grep the --author filter is
completely discarded. This is a bug.
I.e. on git.git:
OK:
$ git log --grep=bar --author=Ævar --pretty=format:%an -100 origin/pu
|sort|uniq -c|sort -nr
5 Ævar Arnfjörð Bjarmason
$ git log --author=Ævar --pretty=format:%an -100 origin/pu |sort|uniq
-c|sort -nr
100 Ævar Arnfjörð Bjarmason
$ git log --grep=bar --invert-grep --author=Ævar --pretty=format:%an
-100 origin/pu |sort|uniq -c|sort -nr

That last command should only find my commits, but instead --author is
discarded.
