src/bin/pax: ar_subs.c buf_subs.c extern.h file_subs.c
Log Message:
pax: don't overwrite destination if -r -w copy fails
Add more error handling to pax -r -w so that any failure
during the copy to the temporary file (including a failed flush)
prevents any existing destination file from being replaced
with the partial (including possibly empty) temporary file.
The partial temporary file is removed. pax still exists non-zero.
Thanks to Michael van Elst (mlelstv@) for the analysis
of the problem in the PR.
Should fix PR misc/33753.
