This shortens, simplifies and regularizes the code significantly.
(Improvements to reflect could make another step.)
Passes all.bash.
One semantic change occurs: The String() method changes
behavior. It used to run only for string formats such as %s and %q.
Instead, it now runs whenever the item has the method and the
result is then processed by the format as a string. Besides the
regularization, this has three effects:
1) width is honored for String() items
2) %x works for String() items
3) implementations of String that merely recur will recur forever
Regarding point 3, example from the updated documentation:
type X int
func (x X) String() string { return Sprintf("%d", x) }
should cast the value before recurring:
func (x X) String() string { return Sprintf("%d", int(x)) }

Change TrimRight and TrimLeft to use these functions.
Incidentally fix minor bug in TrimRight.
Add some test cases for this.
YMMV whether it's worth saving the closure allocation.

Cannot assume that g == m->curg at time of signal.
Must save actual g and restore.
Fixes flaky crashes with messages like
throw: malloc mlookup
throw: malloc/free - deadlock
throw: unwindstack on self
throw: free mlookup
(and probably others) when running cgo.

There's only one Go object file per package now,
so there's no need to parse the metadata and merge
metadata from multiple files. Just save the original
and use it as __.PKGDEF verbatim.

This avoids a crash when using cgo where glibc's malloc thinks
that it can use some of the memory following the symbol table.
This fails because the symbol table is mapped read-only, which
affects the whole page.

Although technically incorrect, we want this in order to parse X.509
certificates where a wildcard hostname ("*.example.com") has been put
into a PrintableString.

* Code for assignment, conversions now mirrors spec.
* Changed some snprint -> smprint.
* Renamed runtime functions to separate
interface conversions from type assertions:
convT2I, assertI2T, etc.
* Correct checking of \U sequences.
Fixes#840.
Fixes#830.

(caused certain files to not be idempotent under gofmt)
- corrected golden files for go/printer
- slightly simplified some code in nodes.go (no impact on formatting)
- these changes have no impact on gofmt output of .go files under src, misc
fallthrough statement considered harmful!

Time (us) to draw a 200x200 src onto an image.RGBA dst with the Over
operator. Each case was measured three separate times, and the sorted
times are reported.
Fill case (where src is an image.ColorImage):
Before:
7438, 7511, 7526
After:
3073, 3087, 3102
Copy case (where src is an image.RGBA):
Before:
9506, 9510, 9563
After:
5262, 5300, 5344

charclass to avoid unnecessarily iterating over ranges.
Also, use the fact that IntVector is an []int to avoid method calls.
On my machine, this brings us from ~27500 ns/op to ~17500 ns/op in the benchmark I've added (it is also faster in the case where a range check
doesn't help, added a benchmark for this too.)
I'd also like to propose that "[]", and "[^]" be disallowed. They aren't useful as far as I can tell, they aren't widely supported, and they make reasoning about character classes a bit more complicated.

(compiler bug stops complex from being renamable,
so it can't be tested but the code is there)
