Lay out the doc and write text for the minor changes.
(I left the net ones for someone who understands them better,
or for someone to describe them to me better so I can write them.)
Much still to do.
Delete go1.2.txt so there's only one thing to update.

The huffmanDecoder struct appears to be intented for reuse by calling init a
second time with a second sequence of code lengths. Unfortunately, it can
currently panic if the second sequence of code lengths has a minimum value
greater than 10 due to failure to reinitialize the links table.
This change prevents the panic by resetting the huffmanDecoder struct back to
the struct's zero value at the beginning of the init method if the
huffmanDecoder is being reused (determined by checking if min has been set to a
non-zero value).
Fixes#6255.

Currently lots of sys allocations are not accounted in any of XxxSys,
including GC bitmap, spans table, GC roots blocks, GC finalizer blocks,
iface table, netpoll descriptors and more. Up to ~20% can unaccounted.
This change introduces 2 new stats: GCSys and OtherSys for GC metadata
and all other misc allocations, respectively.
Also ensures that all XxxSys indeed sum up to Sys. All sys memory allocation
functions require the stat for accounting, so that it's impossible to miss something.
Also fix updating of mcache_sys/inuse, they were not updated after deallocation.

For some long filenames the USTAR-split code does not work
correctly. It is wrongly assumed that the path would not be too long,
but it is.
The user visible result was that a filename was split, but it still
caused an error.
The cause was a wrongly calculated nlen. In addition I noticed that
at this place it is also seems necessary to check if the prefix will
fit in the 155 chars available for the prefix.

Old example referenced global var from multiSorter.Sort and ignored it's argument.

* Sort imports by import path, then import name, then comment. Currently, gofmt sorts only by import path.
* If two imports have the same import path and import name, and one of them has no comment, remove the import with no comment. (See the discussion at issue 4414.)

This message was helpful for pre-Go 1 users updating to Go 1.
That time is past. Now the message is confusing because it
depends on knowing what pre-Go 1 looked like.

Make sure we never pass a timer into timerproc with
a negative duration since it will cause other timers
to never expire.

O_SYNC changes only on linux-arm (and linux-arm-cgo), but
changes to match O_SYNC on linux-{386,amd64} and what Linux
upstream now uses. See discussion and links on

cmd/cc: bv.c imports libc.h twice
When using the Plan 9 compiler, the invocation
#include <../ld/textflag.h>
works for the toolchain, but not for the MACH library.
Module cmd/cc/bv.c includes libc.h and "cc.h", which in
turn also includes libc.h. In the Plan 9 context, this
causes a number of duplicate definitions.

These tests were suggested in golang.org/issue/6080.
They were fixed as part of the new nil pointer checks
that I added a few weeks ago.
Recording the tests as part of marking the issue closed.

This should have been part of revision 16731:cdedb129e020, but
I missed it. This fixes printing local variables when doing
an external link.

DeepEqual caches addresses of compared values
each time it visits addressable values. This is
more expensive than actually comparing them in
the common case of large slices of bytes or integers.
Also add a fast path for slices with identical
underlying array.

The underlying parse tree is visible in text/template, so it should be visible here.
Done by copying the underlying *parse.Tree up to the top level of the struct, and then making sure it's kept up to date.

Based on an old suggestion by rsc, it compares the second
and following arguments to the first.
Unfortunately the code cannot be as pretty as rsc's original
because it doesn't require identical types.
