We didn't mention this explicitly during our discussions,
but I think it fits the "identical types are spelled identically"
rule that we used.

Currently to install a command, you have to manually
goinstall each of the remote packages that it depends on.
This patch lets goinstall P work where P is
contains files in package main.
It does not actually build the package, but
it installs all of its dependencies and prints a message
to that effect.

Based on the review of CL 1723044, I've changed the installation instructions
for the vim syntax files to suggest symlinking the files rather than copying
the files. Also the wording has changed to be more consistent.

x.go:13: cannot use t (type T) as type Reader in assignment:
	T does not implement Reader (Read method requires pointer receiver)
x.go:19: cannot use q (type Q) as type Reader in assignment:
	Q does not implement Reader (missing Read method)
		have read()
		want Read()
x.go:22: cannot use z (type int) as type Reader in assignment:
	int does not implement Reader (missing Read method)

x.go:24: too many arguments to conversion to complex: complex(1, 3)

This sets up vim to work out of the box with go programs as long as syntax
highlighting is enabled. Both files must be copied to the vim runtime
directory in order for the file-type detection and syntax loading to work.

This CL replaces my earlier https://golang.org/cl/1640044/show
in which Continue handling was explicit.  Instead, this CL makes
it automatic.  Reading from Body() is an implicit acknowledgement
that the request headers were fine and the body is wanted.  In that
case, the 100 Continue response is written automatically when the
request continues the "Expect: 100-continue" header.

the text is erroneous UTF-8.

Fix a bug that caused it to ignore field widths.

R=rsc

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.
