This patch teaches merge a new setting, merge.options, which is
processed before any of the other merge configuration settings. It may
be used to establish a default which can then be overridden by more
specific branch.<name>.mergeoptions (or, obviously, command-line
switches).

Which is what this version does. I also made the explanation of this behavior
in the man page more explicit.
