Not if we want to keep the existing behavior of putc, which only
returns EOF when the whole call should fail.

Perhaps there's some misunderstanding here, because I didn't
understand why did you suggest to put this snippet into _flsbuf, and
why did you say ``so that it acts like a "disk full" condition when
the string buffer is empty''.  Could you please describe the situation
which you had in mind?
