[PATCH v2 0/1] Support `git reset --stdin`

This feature was missing, and made it cumbersome for third-party tools to reset a lot of paths in one go.

Support for --stdin has been added, following builtin/checkout-index.c's example.

Changes since v1:

- adjusted commit message to explain why we read everything before
  resetting

- fixed synopsis (`--stdin` does not work with `-- <path>...`)

- avoid handling patch_mode twice

- use PATHSPEC_LITERAL_PATH to avoid interpreting input as wildcards

Johannes Schindelin (1):
  reset: support the --stdin option
