sort: don't dump core when merging from input twice

* NEWS: Document this.
* src/sort.c (avoid_trashing_input): The previous fix to this
function didn't fix all the problems with this code.  Replace it
with something simpler: just copy the input file.  This doesn't
change the number of files, so return void instead of the updated
file count.  Caller changed.
* tests/misc/sort-merge-fdlimit: Test for the bug.
