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.]
