I'm still not fully convinced we needed this (if you ALWAYS
over-allocate the array large enough for a NULL terminator, including in
VIR_APPEND_ELEMENT and friends), but it's easier to let it in than to
force you to work around it.  I would like to see coverage added in
tests/virstringtest.c, though.
