Surprising semantics of "git add file"

Surprising semantics of "git add file"

[Ulrich Windl]

Hi!

Reading the manual, I realized that "it is the way it is (it works as documented)", but to me it's surprising, meaning: I feel it's wrong:
(git-2.16.4)
I have staged several files, and then I do "git add -interactive file" to add some selected changes from file.
After that a "git diff --cached file" just shows the changes added interactively, but when I "git add file" to commit those changes), even the unstaged changes from file are committed.
I feel this is inconsistent: At least "git diff --cached file" should behave like "git commit file", meaning "git commit file" should be fixed IMHO.
Or are there any reasonable use cased for that?

Regards,
Ulrich Windl

Actually things are worse: When I tried to fix the comment for the unexpected commit at least using "git commit --amend", more files were committed!

Did you really mean "git add" here?  It doesn't commit, it adds to the index.

Sorry, you are right "git commit file" I meant. I guess I was distracted when
writing that. Otherwise it wouldn't make any sense.
