** Look up a control setting by its name.  Return a pointer to the Setting
** object, or NULL if there is no such setting.
**
** If allowPrefix is true, then the Setting returned is the first one for
** which zName is a prefix of the Setting name.

** The "settings" command with no arguments lists all settings and their
** values.  With just a SETTING name it shows the current value of that setting.
** With a VALUE argument it changes the property for the current repository.
**
** Settings marked as versionable are overridden by the contents of the
** file named .fossil-settings/PROPERTY in the check-out root, if that
** file exists.
**
** Settings marked as propagating will be overridden if a new value is received
** when pulling from a repository.
**
** The "unset" command clears a setting.
**
** Settings can have both a "local" repository-only value and "global" value
** that applies to all repositories.  The local values are stored in the
** "config" table of the repository and the global values are stored in the
** configuration database.  If both a local and a global value exists for a
** setting, the local value takes precedence.  This command normally operates
** on the local settings.  Use the --global option to change global settings.
**
** Options:
**   --global   Set or unset the given property globally instead of
**              setting or unsetting it for the open repository only
**   --exact    Only consider exact name matches
**   --value    Only show the value of a given property (implies --exact)
**
