When no arguments are given, echo prints a blank line. These two are
equivalent:
$ echo ""
$ echo
Replace the former by the latter.

As the comment said, the subtraction is bogus for multibyte characters.
Fortunately, we can just use last_pos instead of pos to get the correct
position without any subtraction hackery.
This is something that's only been briefly mentioned in the beginning of
the tutorial and all of the closure examples within this subsection
include only one expression between { and }.

The "4.3 Loops" section only describes `while` and `loop`. We then see `for`
used in a code sample at the end of the "13. Vectors and strings" section,
but it's explained for the first time only in the next section --
"14. Closures".
It is worth mentioning it in "4.3 Loops".

Feel free to reword it and commit yourself if you don't like my wording.

Several minor changes:
- The clean-up I mentioned in #6851 (moving functions from deriving/mod.rs to deriving/generic.rs)
- Move `expand_generic_deriving` to a method
- Reimplement `deriving(Ord)` with no dependence on `Eq`
LLVM provides these functions as intrinsics, and will generate calls to
libc when appropriate. They are exposed in the `ptr` module as
`copy_nonoverlapping_memory`, `copy_memory` and `set_memory`.
@graydon: r?
r? @jld or @graydon
The calculation looks right to me, but perhaps one of you two can double check. You two seem like you are doing the most recent work in this sort of area.
