Tab formatting with stream access

I am working on changing gfortran. See PR109358. I hope I am interpreting all this correctly.

I submitted a bug report to Intel, ID 05819114.

This is correct. My choice of wording was more limiting. The way to try to answer this is given by the formatted= and unformatted= keywords of an inquire statement of that file. The possible return values are ‘YES’, ‘NO’, or ‘UNKNOWN’. Especially for an unopened file, a processor is allowed to return ‘YES’ for both values, or ‘UNKNOWN’ for both values. My reply considered only the exclusive case, ‘YES’ for one and ‘NO’ for the other, which is typical for a file that is currently open.
