sort -u: fix a thread-race pointer corruption bug
* src/sort.c (write_unique): Save the entire "struct line", not
just a pointer to one. Otherwise, with a multi-thread run,
sometimes, with some inputs, fillbuf would would win a race
and clobber a "saved->text" pointer in one thread just before
it was dereferenced in a comparison in another thread.
* NEWS (Bug fixes): Mention it.
