Git doesn't "know" which line of code is yours. What it can do is walk
through history to find out: this is "git blame", and you can already do
"git blame | grep ...".

A "git grep --author" would need to blame all files before searching
inside them, or grep first and blame each line in the result to filter
out lines from the wrong author. That would be possible, but relatively
hard to implement and painfully slow. Which probably explains why no one
implemented it yet ...
