As the post [*1*] that triggered e92e9cd3 (Documentation
improvements for the description of short format., 2010-04-23),
which is where the bulk of the format description comes from, says,
this is "Patches welcome" ;-) Some are just covering possible
permutations and it is not surprising if they would not appear in
practice.

I doubt this is possible in practice; once you do not have the entry
in the index, we do not even look at the working tree file, so it
would be unusual to see M in the second column.

When you are using higher-level machinery to merge, "we added, they
left it missing" (i.e. bar that has only stage #2) is automatically
resolved to an addition by the trivial merge machinery. The "they
added, we left it missing" (i.e. baz with only stage #3) case is
identical. Also "both of us removed" (i.e. foo that has only stage
#1) is resolved to a deletion by the trivial merge machinery. Hence
you would not see these three unless you are developing Git using a
low-level plumbing machinery.
