It seems perfectly appropriate:
If the output was truncated due to this limit then the return
value is the number of characters (not including the trailing
'\0') which would have been written to the final string if
enough space had been available.
What problem do you see?
Note that I don't want to fix unnecessary memory usage with that
but several reallocs in case some args are large.
