After you find out an earlier resolution you told rerere to use was a
mismerge, there is no easy way to clear it.  A new subcommand "forget" can
be used to tell git to forget a recorded resolution, so that you can redo
the merge from scratch.

diff --git a/rerere.c b/rerere.c

+		 &mmfile[2], "theirs", 0);

When you simply call ll_merge(), will it obey any merge drivers that are defined in .gitattributes? Do we care about them?

I already had an implementation of "rerere forget" before you presented this solution, but it relies on that the user calls "checkout --conflict=merge" first. One reason (besides its simplicity) was that it does not have to care how the merge is computed.

[I haven't submitted my solution, yet, because I haven't had the time to do this large merge where I expect to make use "rerere forget", testing its usefulness.]
