dbLoadTemplate allows you to provide fewer pattern-values than pattern-names 
and only defines macros for the pattern-values you've given it.  This allows 
global and command-line settings to provide defaults, although of course you 
can only omit values from the end of the list.  It also used to silently 
accept more pattern-values than pattern-names, but it now prints a warning 
message if you do that (and discards them as before).

I don't know whether MSI supports this behaviour or not, but I think we have 
to keep it in dbLoadTemplate.
