Subject: Modify wrbuf_put_zquery and wrbuf_scan_term so the generated
X-Git-Tag: YAZ.2.0.30~60
X-Git-Url: http://jsfdemo.indexdata.com/cgi-bin?a=commitdiff_plain;h=30e703f75c26ad4b564e380d586d122edd49046d;p=yaz-moved-to-github.git

Modify wrbuf_put_zquery and wrbuf_scan_term so the generated
PQF code is valid for reparsing.
