This commit removes a number of deprecated flags from the compiler:
* opt-level => -C opt-level
* debuginfo => -C debuginfo
* print-crate-name => --print crate-name
* print-file-name => --print file-names
* no-trans => -Z no-trans
* no-analysis => -Z no-analysis
* parse-only => -Z parse-only
* dep-info => --emit dep-info
This commit also moves the --pretty flag behind `-Z unstable-options` as the
pretty printer will likely not be stable for 1.0
cc #19051
**Breaking change**: `VecMap::into_iter` now consumes the `VecMap`. To fix it you should pass the VecMap by value instead of by reference.

`x in y` is more Pythonic than `y.find(x) != -1`. I believe it runs quite a bit faster as well (though it's probably not a bottleneck of the Travis builds):
```bash
$ python -m timeit '"abc".find("a") != -1'
1000000 loops, best of 3: 0.218 usec per loop
$ python -m timeit '"a" in "abc"'
10000000 loops, best of 3: 0.0343 usec per loop
```
After PR #19766 added implicit coersions `*mut T -> *const T`, the explicit casts can be removed.
(The number of such casts turned out to be relatively small).
Increases the delay of the search box to 500ms after key up. I tried
adding a three character minimum for setting the delay, but didn't find
it very useful.
Should close#20095
@Jurily, your input is welcome!
Two errors in `std::sync` are currently missing implementations of the standard error trait because they contain types which aren't `Send`.
This PR therefore requires #21312.
rust.nanorc provides syntax highlighting for Rust. An attempt has been made to make the syntax highlighting look good on both dark and light terminals. Issue #21286.
This PR is dedicated to @substars and nano-lovers everywhere.
As discussed with @aturon, this PR removes the `Send` bound from `std::error::Error`, allowing us to implement `Error` for error types containing non-`Send` types. Current examples include `PoisonError` and `TryLockError` from `std::sync` which contain a Guard that we don't want sent between tasks.

Brings the rustdoc man page in sync with the options specified in
src/librustdoc/lib.rs. The text was taken verbatim, but I tweaked the
order to be (what I think is) somewhat logical.
This should close#13622.
This removes the extra "the" from the phrase "the the Rust Programming Language book", which isn't particularly grammatical, in stub documents introduced in #20802 to direct users from the old guides to the corresponding sections of the book.
