Flang, while compiling the program
```
program t
write(*,'(f3.0, )') 1.0
end program
```
throws this error
```
Unexpected ',' before ')' in format _expression_
write(*,'(f3.0, )') 1.0
^
```
While gfortran, when compiled with the flag `-fdec-blank-format-item`, successfully compiles the program with no errors. If the flag is not used, it emits:
```
write(*,'(f3.0, )') 1.0
1
Error: Missing item in format string at (1)
```
Should flang support this behavior similar to gfortran (-fdec-blank-format-item), or is the current rejection the intended behavior?
GNU Fortran documentation mentions that a comma with no following format descriptor may be permitted with -fdec-blank-format-item as a legacy DEC extension , refernce link :[Commas-in-FORMAT-specifications]( https://gcc.gnu.org/onlinedocs/gcc-13.4.0/gfortran/Commas-in-FORMAT-specifications.html)
