Silent truncation should require explicit coding.

Strlcpy is completely bogus.


Both snprintf() and strlcpy() make it fairly easy to detect whe the
buffer was too small, which is more than I can say for strncpy().
It is up to the programmer to actually check the return value.

That said, I certainly agree that proceeding with a truncated buffer
is the wrong thing to do.  Many (but not all) systems these days
provide asprintf() which dynamically allocates its buffer which can
solve a lot of these problems.
