I didn't give tzafrir very much time to test this, but if he does 
still have remaining issues, he is welcome to 
re-open this bug, and we'll do what is called for.

I reproduced the problem, and tested the fix, so I hope I
am not jumping by just going ahead and committing the fix.

The problem was with what file_save does with templates; 
firstly, it tended to print out multiple options:

[my_category](!)(templateref)

instead of 

[my_category](!,templateref)

which is fixed by this patch.


Nextly, the code to suppress output of duplicate declarations
that would occur because the reader copies inherited declarations
down the hierarchy, was not working. Thus:


 [master-template](!)
 mastervar = bar


 [template](!,master-template)
 tvar = value


 [cat](template)
 catvar = val


would be rewritten as:

 ;!
 ;! Automatically generated configuration file
 ;! Filename: experiment.conf (/etc/asterisk/experiment.conf)
 ;! Generator: Manager
 ;! Creation Date: Tue Mar 18 23:17:46 2008
 ;!
 
 [master-template](!)
 mastervar = bar

 
 [template](!,master-template)
 mastervar = bar
 tvar = value

 
 [cat](template)
 mastervar = bar
 tvar = value
 catvar = val

This has been fixed. Since the config reader 'explodes' inherited
vars into the category, users may, in certain circumstances, see
output different from what they originally entered, but it should
be both correct and equivalent.
