Re: [PATCH 0/5] "diff --stat" counting fixes

[Antoine Pelisse <apelisse@gmail.com>]

Hi Junio,

That does make a lot of sense and I would have indeed missed a couple
of things here.

I've been thinking about that "Unmerged" line quite a lot, and I can't
get myself any good reason to keep it.
Would you mind taking a couple of minutes to make it clear ?

I feel like (but I can obviously be wrong):
1. The info is redundant. When performing a merge, all diffs (without
--staged flag) are unmerged
2. While status shows the line once, while diff shows the diff for the file
once, while diff --shortstat counts the file once, diff --stat shows two
lines for the file.
3. diff --numstat shows two lines for the same file. As a script
writer (I guess that's what it's meant for), I would definitely expect
uniqueness in third column/filenames.

Cheers,
Antoine
