Time is a tiny struct, so the compiler copies a Time by
copying each of the three fields.
The layout of a time on amd64 is [ptr int32 gap32 ptr].
Copying a Time onto a location that formerly held a pointer in the
second word changes only the low 32 bits, creating a different
but still plausible pointer. This confuses the garbage collector
when it appears in argument or result frames.
To avoid this problem, declare nsec as uintptr, so that there is
no gap on amd64 anymore, and therefore no partial pointers.
Note that rearranging the fields to put the int32 last still leaves
a gap - [ptr ptr int32 gap32] - because Time must have a total
size that is ptr-width aligned.
Update #5749
This CL is enough to fix the problem, but we should still do
the other actions listed in the initial report. We're not too far
from completely precise collection.

The existing compilers convert empty strings to empty
but non-nil byte and rune slices. The spec required
a nil byte and rune slice in those cases. That seems
an odd additional requirement. Adjust the spec to
match the reality.
Also, removed over-specification for conversions of
nil []byte and []rune: such nil slices already act
like empty slices and thus don't need extra language.
Added extra examples instead.
Fixes#5704.

The old code worked, somewhat on accident, but was confusing,
and had a useless assignment to the inner err. It worked
because url.Parse parses just about anything, so the outer err
was always nil, so it always fell through to the bottom return
statement, even without the "err = nil" line.
Instead, just have two return statements, and add a comment.

TLS clients send ciphersuites in preference order (most prefereable
first). This change alters the order so that ECDHE comes before plain
RSA, and RC4 comes before AES (because of the Lucky13 attack).
This is unlikely to have much effect: as a server, the code uses the
client's ciphersuite order by default and, as a client, the non-Go
server probably imposes its order.

This basic Vim ftplugin sets the 'comments' and 'commentstring'
settings to sensible values. Future filetype settings for Go
would go in the same file.
The ftplugin was added as misc/vim/ftplugin/go/go.vim, this way
the installation instructions in readme.txt remain valid.
