Added an attachment with the diffrence to the current file
version. This har three parts. The first is just updatepos
inserted at the correct places in the function goahead. The
second is from the part of the goahead function which
handles the &-characters. I had a hard time making it work
with the current model and changed it to a version inspired
by the same part of the goahead-function in HTMLParser.py.
The last is the printouts in the testfunction to check if
the function performs ok.
