git log docs suggest it should not do this:

       -s, --no-patch
           Suppress diff output. Useful for commands like git show
that show the patch by default, or to cancel
           the effect of --patch.

Couldn't find anything in a search of the archives of this mailing
list, although that's obviously far from conclusive. Seems to be
longstanding, as it was mentioned on StackOverflow back in 2015:
