-Subject: [PATCH] bootstrap: Restore missing --bulk-dirs for rust-docs,
- rustc-docs
-
-The --bulk-dirs argument was removed for rust-docs in commit
-c768ce138427b1844c1f6594daba9c0e33928032 and rustc-docs in commit
-8ca46fc7a83734c9622f11f25d16b82316f44bcc (#79788), presumably by
-mistake; that slowed down installation of rust-docs from under a
-second to some twenty *minutes*.  Restoring --bulk-dirs reverses this
-slowdown.
-
-Fixes #80684.

-Subject: [PATCH] Increment `self.index` before calling
- `Iterator::self.a.__iterator_get_unchecked` in `Zip` `TrustedRandomAccess`
- specialization
-
-Otherwise if `Iterator::self.a.__iterator_get_unchecked` panics the
-index would not have been incremented yet and another call to
-`Iterator::next` would read from the same index again, which is not
-allowed according to the API contract of `TrustedRandomAccess` for
-`!Clone`.
-
-Fixes https://github.com/rust-lang/rust/issues/81740
-
