asterisk users - Oct 2009 - SPRINTF option : format %1$s not supported

Hi,

With 1.6.1.7-rc2, doc says:
select*CLI>
  -= Info about function 'SPRINTF' =-

[Syntax]
SPRINTF(<format>,<arg1>[,...<argN>])

[Synopsis]
Format a variable according to a format string

[Description]
Parses the format string specified and returns a string matching that
format.
Supports most options supported by sprintf(3).  Returns a shortened string
if
a format specifier is not recognized.



I'm trying use sprintf option allowing to swap argument display according
format string.
More precisely, I'm trying to this "%1$s" specifier (which means
"use 1st
argument").
Then, the reply is :
ERROR[3185]: func_strings.c:547 acf_sprintf: Format type not supported:
'%1$' with argument '1234'

Though the message is clear, before giving up, I thought I should ask here
if someone could successfully use the
"%1$s" specifier (which is very useful when you want to localize some
messages or output some command strings).


Regards

Nope.  Dollar ($) format specifiers are not supported at all.  Given that the
arguments to SPRINTF are specified in a string, you could simply repeat an
argument where necessary, which is why I never bothered implementing any
of the positional formats.

My initial (imho) impression is that  localizations in the code, are in
general a bad way to approach
localization in general. The localizations should be located neither in
Asterisk code nor in dialplan code.

I know, I know, that such code already exists, but that's still not making
my assertion false...
