git stash push --patch offers skip-worktree hunks

Hi,

I'm using this to hide some locally modified files from accidental commit:

  git update-index --skip-worktree ...

Doing `git stash push` does not result in the above modifications being
stashed. But, doing `git stash push --patch` asks me about hunks in the
files which were flagged to skip-worktree. Instinctively, this feels wrong.
The docs also say:

  Interactively select hunks from the diff between HEAD and the working tree
  to be stashed.

What do you think?

regards,
