This was established as solution to PR48488 where we had two choices for
selecting the significant digits. Nine significant digits was established as
a requirement to guarantee round trip in all cases. The char4_iunit_1.f03
test case was revised because after we corrected the formatting in PR48906,
it started to fail and I observed the test case was looking for the wrong
number of significant digits.


Based on this, I would suggest we leave it as I have it, which is correct.

I'm afraid it's not.


1.23450002E-06 has nine significant digits. That's how it should be.

We don't want 1PG16.9E2 editing for list-directed and G0,
but G16.9E2 for the F editing range and 1PE16.8E2 editing for the E range.


This is to make sure the result always has nine significant digits,
whether in the F or E range.


My bad, I counted across wrong. Working on it. Coffee deficiency in the early morning.
