--- Comment #16 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- I think I was not being very clear when I opened pr113897. nX descriptors are very similar to TR code and I meeantt to take care of those in the 113897. The reason for the separate PR is that the problem is completely different than this one which is relates to the use of stream I/O. The consecutive tabs or spaces require looking ahead in the format string and effectively squashing these before writing the next actual data. This was my plan for PR113897.
