Hello,

$ git help log | grep exit-code
           problems are found. Not compatible with --exit-code.

What --exit-code does in "git log"?

It doesn't.  That is why it is not listed.

I disagree that --exit-code does nothing: it indicates whether the
listed log is empty.  So for example

git log -1 --exit-code a..b > /dev/null

can be used to figure out whether "a" is a proper ancestor of "b" or
not.
