[PATCH] log: Update log.follow doc and add to config.txt

["Eric N. Vander Weele" <ericvw@gmail.com>]

Documentation/config.txt does not include the documentation for
log.follow that is in Documentation/git-log.txt.  This commit adds the
log.follow documentation to config.txt and also updates the wording to
be consistent with the format that is followed by other boolean
configuration variables.
