[Help-smalltalk] 1e-4 printing bug

Previously in the list someone reported a bug in float printing:

There is a bug in Float printing which I attached a patch. the variable
allNines should really mean all nines except the last one, so if the
last one round up, which  may not be 9 itself,  still can cause the
whole digits round up and eat a leading zero in printing.

Here is a patch to fix:
