The 50 character limit is for the first line, try "git log
--pretty=oneline" and it should be obvious why.
The rest of the lines can be longer, 72 is another popular choice.

I'm wondering if the default commit-msg hook should have something like:
perl -ne '$lim = (50,0,72)[($.>3?3:$.)-1];
            chomp;
            if (length($_) > $lim) {
              print STDERR "Line $. of commit message exceeded $lim
characters";
              exit 1;
            }' $1

to more forcefully suggest what's in the manual, like the pre-commit hook does.

(I wish I'd had something like this when one of the devs here pushed a
commit with a 346-line message,
just listing what files he was changing...doh)
