Interesting.  While driving to work this morning I had the same
thought.  A revision that does not appear in the output from

	for file in $(list of files the commit touches)
        do
		git blame v2.6.17..v2.6.18 -- $file
	done

can safely be omitted from the shortlog, because later changes
fully supersedes it.

I think the list of "important" changes is an interesting
problem, but the importance may not directly be related to the
number of paths a patch touches (e.g. "you reorder the members
of a structure everybody uses in one include file and everything
starts performing faster due to better cache behaviour" would be
a few lines of a single header file).  Also better clues to
judge the importance would be found outside the repository.
"The patch discussed by many people on the list" and "the patch
that had very many iteration to get in the final shape" would
certainly be interesting ones, but that information is often not
found in the repository.
