[PATCH v2 11/12] t5524: test --log=1 limits shortlog length

[Paul Tan <pyokagan@gmail.com>]

While git-pull supports --log and passes the switch to git-merge, it
does not support --log=<n>, ignoring the value <n>.

This is not only at odds with the documentation of git-pull, it's also a
undesirable limitation as <n> could simply be passed to git-merge as
well.

Implement a failing test that demonstrates this.
