upstream commit

Even when only writing an unescaped character, the dst
 buffer may need to grow, or it would be overrun; issue found by tb@ with
 malloc.conf(5) 'C'.

While here, reserve an additional byte for the terminating NUL
up front such that we don't have to realloc() later just for that.

OK tb@
