--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
Thanks for the strncat suggestion. That seems quite doable. I'll try to find
some time to look into it.
I explored some of the other ideas when I implemented the GCC 7 sprintf
optimization (-fprintf-return-value) and warnings (-Wformat-overflow and
-Wformat-truncation) but they didn't seem applicable in enough situations (when
all or at least some of the arguments were constant) to justify either the
additional complexity or the space overhead.
