This implements the trait for vector iterators, replacing the reverse iterator types. The methods will stay, for implementing the future reverse Iterable traits and convenience. This can also be trivially implemented for circular buffers and other variants of arrays like strings and `SmallIntMap`/`SmallIntSet`. The `DoubleEndedIterator` trait will allow for implementing algorithms like in-place reverse on generic mutable iterators. The naming (`Range` vs. `Iterator`, `Bidirectional` vs. `DoubleEnded`) can be bikeshedded in the future.
just avoid giving an inline hint in the first place
Indentation now works correctly on subsequent lines of a multi-line
comment, whether there are leaders (` * `) or not. (Formerly it was
incorrectly doing a two-space indent if there was no leader.)
By default, this no longer puts a ` * ` leader on `/*!` comments, as
that appears to be the current convention in the Rust source code, but
that can easily be re-enabled if desired:
let g:rust_bang_comment_leader = 1
