xstrdup() would fail during the xmalloc() call which would cause a
call to fatal() and it would quit.  So the check is really not
valid for that reason.  Which is why I figured you were doing it for
strrchr().  because xmalloc(0) is valid.

Noted.  And either it may have to go into an FAQ begging people to upgrade
at least their glibc or add in another sprintf() hack type check.
