In version 5:

N[Pi,20]
InputForm@%

3.1415926535897932385

3.141592653589793238462643383\
58737222874`20.

InputForm[%,NumberMarks\[Rule]False]

3.1415926535897932385

But I agree the bug-reporting and repair process is broken.

It needs to be much more transparent -- if what we think and feel counts 
for anything.
