OK, but "stage" can be a noun.
Here is one of the definitions:
: a center of attention or scene of action
This definition doesn't imply what the action is about, but
"commit stage" should be perfectly aligned with that definition.
Here's another one:
: one of two or more sections of a rocket that have their own fuel and engine
These rocket stages need to be prepared before the launch, just like
changes before a commit. A commit can be thought of as a single-stage
rocket, and just like parts can be added and removed from this
single-stage before launch, so can changes before a commit.
I understand why this might not seem natural to native English speakers,
but it's perfectly aligned with the etymology of the word "stage"
(to stay).
I'm not saying it should be thought of this way, merely that it *can*.
Either way, I also thought about adding yet another command
`git staging-area` and diff instead of an option be a subcommand:
`git staging-area diff`, but to be frank I don't think anybody would end
up using this command, especially without default aliases (like
`git sa`). So I opted against it.
Even though `git stage --diff` is not ideal, it's the least bad option
in my option.
