libgfortran: Adjust bytes_left and pos for access="STREAM".
During tab edits, the pos (position) and bytes_used
Variables were not being set correctly for stream I/O.
Since stream I/O does not have 'real' records, the
format buffer active length must be used instead of
the record length variable.
PR libgfortran/109358
libgfortran/ChangeLog:
* io/transfer.c (formatted_transfer_scalar_write): Adjust
bytes_used and pos variable for stream access.
gcc/testsuite/ChangeLog:
* gfortran.dg/pr109358.f90: New test.
