un-xfail test for #8498 and replace prints w/ asserts
std: rename fmt::Default to `Show`.

This is a better name with which to have a #[deriving] mode.

Closes #8498
std::fmt: prepare to convert the formatting traits to methods, and work
around the lack of UFCS.

The further work is pending a snapshot, to avoid putting #[cfg(stage0)]
attributes on all the traits and duplicating them.
Remove the SNAP line to work around #11985.
auto merge of #11948 : huonw/rust/show, r=alexcrichton

- renames `Default` to `Show`
- introduces some hidden `std::fmt::secret_...` functions, designed to work-around the lack of UFCS (with UFCS they can be replaced by referencing the trait methods directly) because I'm going to convert the traits to have methods rather than static functions, since `#[deriving]` works much better with true methods.

I'm blocked on a snapshot after this. (I could probably do a large number of `#[cfg]`s, but I can work on other things in the meantime.)
Remove rustpkg.

I'm sorry :'(

doc: use backticks for code-in-comments.
auto merge of #11996 : lecram/rust/master, r=pcwalton

This Pull Request aims to add backticks to all instances of code inside comments in snippets present in tutorial.md. It also includes backticks for filenames in the same conditions. See #11796 for motivation.
