Many users prefer to always use --follow with logs. Rather than
aliasing the command, an option might be more convenient for some.

Why not just alias log=log --follow?
At Twitter, we manage git config centrally, but we also allow users to
add their own aliases. We would like to turn log.follow on globally,
while not messing up any aliases users already have for log.
Also, some users might have different log aliases for different
repositories, but want to manage --follow globally.
And in the future, we might want to make log --follow the default (it
is what I usually want), so it would be nice to provide a way for
users to turn that off globally from a config option.
