Robert Griesemer eaae95fa3d scanner: fix Position returned by Scan, Pos
The implementation of the position computation
was surprisingly broken. Implemented fixes and
added extra test cases.

There is a slight interface change: Calling
Pos() returns the current position; but if
called before Scan() that position may not
be the position of the next token returned
by Scan() (depending on the scan settings
and the source text) - this in contrast to
the original comment.

However, after calling Scan(), the Scanner's
Position field reports the position of the
scanned token, as before.

Fixes #1327.

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.

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.
