Patch: rearrange a long line in sql's documentation

[George Zarkadas]

This is minor really, but since it had showed up during the lintian scan
(see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=518696 for
reference) I will report it:

The DBURL syntax line in sql documentation is longer than man would be
happy with. 

The following patch handles this in the best way I could thought.

 A DBURL has the following syntax:
-[sql:]vendor://[[user][:password]@][host][:port]/[database][?sqlquery]
+[sql:]vendor://[connection]/[database][?sqlquery]
+
+The connection part has the form:
+[[user][:password]@][host][:port]
 
 See the section DBURL below.
