--- Comment #2 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
I am using my copy of the F2018 standard.

"13.8.1.2 The Tn edit descriptor indicates that the transmission of the next
character to or from a record is to occur at the nth character position of the
record, relative to the left tab limit. This position can be in either
direction from the current position."

Currently we do this:

1234567890123
1234         0123
1234         0123

We should do this:

1234567890123
1234     0123
1234     0123

"13.5 (3) During formatted stream output, processing of an A edit descriptor
can cause file positioning to occur (13.7.4)."

I am not finding anything that says file positioning is not allowed.  The above
is just elaborating different ways that an A edit descriptor affects the
positioning.  Positioning is always done no matter what with the T specifier.

Regardless, I do need to fix this.
