Subject: Output file generated at very end rather than at beginning.
X-Git-Tag: v3.0.45~19
X-Git-Url: http://jsfdemo.indexdata.com/cgi-bin?a=commitdiff_plain;h=1fb26db29805d4822763c205358f394725b0f02c;p=yaz-moved-to-github.git

Output file generated at very end rather than at beginning.

Output is produced to a temporary file (.tmp) and then renamed at
very end if operation is succesful.
