Subject: don't fork sh/dx on simple query
X-Git-Url: http://dxcluster.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=743a03b3b060fbff8579503647a01722fb634cb1;hp=743a03b3b060fbff8579503647a01722fb634cb1;p=spider.git

don't fork sh/dx on simple query

If the query does not contain an "expression" (or even just a
callsign and is garanteed to be satified by the cache - if it is
enabled - then do not fork / run as a sub command.

So 'sh/dx', 'sh/mydx' with or without a count will be run from
the cache - if it is enabled.
