Russ Cox 4591cd631d unicode: performance improvements (API change) 
*** There is an API change here: the introduction of the
LatinOffset int in the RangeTable struct. ***

* Avoid checking Latin range multiple times for non-Latin runes.
* Use linear search when it is faster than binary search.

go test -calibrate runs the calibration for where the linear/binary
crossover should be.

benchmark                       old MB/s     new MB/s  speedup
BenchmarkFields            36.27        41.43    1.14x
BenchmarkFieldsFunc        36.23        41.38    1.14x

The speedup here is evenly split between the linear scans
and the LatinOffset change. Both are about 1.07x.

README 

This is the source code repository for the Go programming language.  

For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install.html in your web browser.

After installing Go, you can view a nicely formatted
doc/install.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install.html.

Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README).  You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:

    export GOROOT=$HOME/go
    export PATH=$PATH:$GOROOT/bin

See doc/install.html for more details.
