I made the second version of that fix in a hurry and just noticed that
after I submitted the code. I hesitated to send a changed fix right
away, because I had doubts that this is really the best solution.
Now I think we better should make asInteger be equivalent to asNumber

asInteger
~    ^Integer readFromString: self

and have a new method firstInteger (or extractFirstInteger) that does
the job of former asInteger, but to return 0 instead of nil in case
there are no digits in the string. This would be the changes for the
senders

asInteger            firstInteger
asSignedInteger      firstInteger
asUnsignedInteger    firstInteger abs
