See attached. Honestly I stared at this for hours and gave up on it more
than once since the problem first showed up. As usual, once one sees it,
it is almost obvious.
Feel free to exercise this thing since the area of tabbing has been so
troublesome.
Regression tested on x86_64.
OK for mainline?
I have only lightly tested it, but did not see any issue here.
So OK from my side.
Thanks for the patch!

libfortran: [PR114618] Format produces incorrect output when contains 1x
When tabbing left or right it is possible to land in the format buffer
where some text is over written or skipped improperly. The bad
formatting
depended on whether stream I/O is used or regular I/O. The max
position
has to be calculated correctly in these situations.
One existing test case is renamed to align with other format T/TL/TR
test cases.

libgfortran/ChangeLog:
* io/transfer.c (formatted_transfer_scalar_write): Determine
possible new max_pos based on file I/O method and adjust
accordingly
gcc/testsuite/ChangeLog:
* gfortran.dg/pr114618.f90: Move to...
* gfortran.dg/fmt_t_10.f90: ...here.
* gfortran.dg/fmt_t_11.f90: New test.
