We should use DialUnix or ListenPacket for unixgram networks
because Dial doesn't take a local UnixAddr.

Change #foo to div#foo to avoid selecting headings
with anchor foo, such as <h1 id="foo">.

(A more extensive change would be to use class
selectors for styling. Perhaps this is better, since id:s
should be unique within a document according to
http://www.w3.org/TR/CSS2/selector.html#id-selectors)

Work around profiling kernel bug with signal masks.
Still broken on 64-bit Snow Leopard kernel,
but I think we can ignore that one and let people
upgrade to Lion.

Add new trivial tools addr2line and objdump to take
the place of the GNU tools of the same name, since
those are not installed on OS X.

Adapt pprof to invoke 'go tool addr2line' and
'go tool objdump' if the system tools do not exist.

Clean up disassembly of base register on amd64.

        If stdout and stderr are indeed the same file (not a tty), which is
        often the case, fully-buffered stdout will make it harder to see

I've elected to omit escaping the output of Marshalers for now.
I haven't thought through the implications of that;
I suspect that double escaping might be the undoing of that idea.

The main change is simple: Both the Directory and DirEntry
struct have an extra field 'HasPkg' indicating whether the
directory contains any package files. The remaining changes
are more comments and adjustments to the template files.

Import paths with spaces are now invalid.

The builders would've caught this if they were running
the long tests.  I've removed the check for short tests
in this package since the current tests are fast enough
already.
