Subject: Recognise number tokens as terms, as well as words and strings.
X-Git-Tag: v1.5~246
X-Git-Url: http://sru.miketaylor.org.uk/?a=commitdiff_plain;ds=sidebyside;h=c77bd4c9ead8ea2dc08e1fadd801a5d01db84a9a;p=cql-java-moved-to-github.git

Recognise number tokens as terms, as well as words and strings.
Don't emit extraneous blank line at end of XCQL output.
Temporarily parse prox parameters in the MA's silly order.
