[Templates] Sorting one element arrays

[Chris Dean]

Sorting one element arrays of hashes seems to automagically change the
type of variable from an Array to a Hash.  This creates problems when, 
for example, sorting before calling FOREACH.

Consider this code:

    [% longarray = [ { name => "Austria", count => 7 }, 
                     { name => "China",   count => 5 }, 
                     { name => "Brazil",  count => 6 }, 
                     { name => "Denmark", count => 7 } ] %]

    [% shortarray = [ { name => "England", count => 9 } ] %]

    longarray = [% longarray %] 

    longarray = [% longarray.sort( "name" ) %] 


    shortarray = [% shortarray %] 

    shortarray = [% shortarray.sort( "name" ) %] 

shortarray turns into a Hash ref after the sort.

The fix seems trivial, but please double check since I'm not exactly
sure what Stash.pm is doing :-)

Chris Dean
