    we can't import "./bug0" on windows, as it will trigger
"import path contains invalid character ':'" error.
    instead, we pass "-D." and "-I." to gc to override this
behavior. this idea is due to remyoudompheng.

This is more in sync with the rest of the package;
for instance, we have functions (not methods) to
deref or find the underlying type of a Type.

In the process use a single bytes.Buffer to create
the string representation for a type rather than
the (occasional) string concatenation.

If an end tag has an attribute that is a quoted string containing '>',
the tokenizer would end the tag prematurely. Now it reads the attributes
on end tags just as it does on start tags, but the high-level interface
still doesn't return them, because their presence is a parse error.

The situation only affects diagnostics but is easy to fix.

returned by nextItem rather than the current state of the lexer.
This is internal only and does not affect the API.

To be filled in by a later CL. I deployed a test version to
App Engine to work on setting the values, so there are
a few records that have this field set already.

That field is breaking the live version, so I have pushed
a new copy with this 1-line change to the live version

I assumed that appengine/datastore was like every other
marshaling and unmarshaling package we have in Go
(for example, encoding/gob, encoding/json, encoding/xml,
and protobuf) and that if it loaded an unknown field it would
just ignore it. Apparently not. Sorry.

Darwin kernels have a bug in accept() where error result from
an internal call is not checked and socket is accepted instead
of ECONNABORTED error. However, such sockets have no sockaddr,
which results in EAFNOSUPPORT error from anyToSockaddr, making
Go http servers running on Mac OS X easily susceptible to
denial of service from simple port scans with nmap.

If a factored import group has a blank line, assume it is dividing
separate groups of imports (e.g. standard library vs. site-specific).
        import (
                "bytes"
                "io"

                "mycorp/package"
        )

The most common case is inserting new standard library imports,
which are usually (stylistically) the first group, so we should drop
"net" in the above example immediately after "io".

Since this logic is getting non-trivial, add a test.
