"git log" does not do merge diffs by default; you need to pass one of
"--cc", "-c", or "-m".
"git show" will do "--cc" by default. Any file that is the same in the
merge result and _any_ of the branches is considered uninteresting here,
and that is what happened in your example. One parent had the file, the
other did not, and you deleted it to match the second parent.
See the "Combined Diff" section of "git help log" for more details.
When debugging merge resolutions, I often find it useful to use "-m",
which diffs separately against _each_ parent (though it is often tedious
to pick through the uninteresting bits, which is why "-c" and "--cc"
were invented in the first place).

Try that with "-m", which will show the merge in question (and another,
more boring merge, which hopefully shows why "-m" is not the default).
