After staring at the data structure around this area for a while, I
think these two patches are OK, especially within the current
structure.  rev_info structure has a set of bits that are marked as
"Diff flags" (some of which are not about diff at all, though; for
example, verbose_header and no_commit_id belong more to the "Format
info" group), and those related to merges do belong there, as they
need more than "here are two tree-like things I want to compare".

So, I'll mark these two patches for 'next' now.

Thanks.
