Sorry folks, the first email was incomplete.  It did not include
the patch for doprnt.c.

DJ's post made me think it may  be wiser to put it in 2.xy then the
bugfix 2.03.

Ok, I don't know if this is the right approach, I simply redefine
the PUTC(ch) macro in  doprnt.c :

/*
Only if the stream is an ouput string, check for buffer overun.
The do {..}while(0) is for atomicity, any compiler should
eliminate the constant condition.
*/
#define PUTC(ch) \
do { \
	if (fp->_flags & _IOSTRG && fp->_flags & _IOWRT && !fp->_cnt) \
		return counter; \
	(void) putc(ch); \
	counter++; \
} while (0)

There is probably other ways, like in _flsbuf() or __putc_raw()
check if we're dealing with a string output and take the appropriate action.

Let me know, what you think.  And I'll resubmit a complete patch
with *.txh, tests etc .. according to the comments, that includes
"forget it, too much trouble".
