If you use both "--word-diff" and "--color-moved", regardless of the
order of arguments, "--word-diff" takes precedence and "--color-moved"
isn't allowed to do anything.
I think "--color-moved" should have precedence over "--word-diff". I
cannot think of a scenario where a user would supply both options, and
actually want "--word-diff" to take precedence. If I'm not thinking
of a scenario where this wouldn't be desired, perhaps whichever is
first as an argument could take precedence.
(The same behavior happens if 4+ lines are moved and
"--color-moved{default=zebra}" is used, but below
"--color-moved=plain" is used to be a smaller testcase.)
Given the following setup:
$ cat << EOF > file
> a
> b
> c
> EOF
$ git add file
$ git commit -m "Added file."
$ cat << EOF > file
> b
> c
> a
> EOF
You can have moved lines colorization:
$ git diff --color-moved=plain
...
[oldMovedColor]-a
b
c
[newMovedColor]+a
You can diff based on words:
$ git diff --word-diff
...
[oldColor][-a-]
b
c
[newColor][+a+}
But, you cannot diff based on words, and have moved lines colorization:
$ git diff --color-moved=plain --word-diff
$ git diff --word-diff
...
[oldColor][-a-]
b
c
[newColor][+a+}
