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

It's still broken because `jemalloc`'s `configure` script doesn't work when the build triple doesn't match the target triple due to missing a way to get the page size. I'm not entirely sure how to pass a hardcoded value to autoconf/configure.
This at least gets it a bit further along.
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`.
