I think a natural way to ask reviewing the recent merges while
showing tricky ones would be to say:
$ git log --first-parent --cc master..pu
But this does not to show what I expect to see, which is an output
$ git log --first-parent --cc -p master..pu
This is only a minor irritation, but I think it might make sense to
make it notice the --cc in the former and turn -p on automatically.
The same for
$ git log --cc next~3..next
which may make sense to turn into "git log -p --cc next~3..next".
When deciding if the above makes sense, there are a few things to
know to be true as prerequisites for the discussion:
* Neither of these
$ git log --first-parent -p master..pu
$ git log -p master..pu
shows any patches, and it is not a bug. No patches are shown for
merges unless -m is given, and when -m is given, we give pairwise
2-way diffs for the number of parents.
* We recently tweaked this:
$ git log --first-parent -m -p master..pu
to omit diffs with second and later parents, as that is what the
user wishes with --first-parent.
* The "--cc" option, when comparing two trees (i.e. showing a
non-merge commit), is designed to show a normal patch. In other
words, you can view "--cc" as a modifier when you request a patch
output format with "-p". For "git show", "--cc -p" is turned on
by default, and giving "-m" explicity (i.e. "git show -m") you
can turn it off and have it do "-m -p" instead.
