That is an actionable improvement idea to introduce a synonym ;-)
But in general, the way the internal "git grep" machinery is exposed
to the commands in the "git log" family is very limited. With "git
grep", it is quite straight-forward to say "report hits for lines
that has this but not that"
$ git grep -e this --and --not -e that
but because that the commands in the "log" family already use
"--not" for a quite different purpose, "git log --grep" cannot even
express something similar, even to find hits on a single line, let
alone finding hits on two different lines (i.e. one on the "author"
header, the other in the message part, of the commit object).
