Summary:                    [patch] The CUT function does not show the leading
field-separators until it finds a value.
Description: 
The CUT function does not show the leading field-separators if the first
values are NULL and will start functioning normal if it does find a value.

For example: 
1 - ${CUT(1---4-5-6--8--,,1-5)} results in: 1---4-5 (CORRECT)
2 - ${CUT(1---4-5-6--8--,,6-10)} results in: 6--8-- (CORRECT)
3 - ${CUT(1---4-5-6--8--,,2-10)} results in: 4-5-6--8-- (INCORRECT!,
should be: --4-5-6--8--)

In second and third statement the TRAILING separators are shown.
However the third statement should also show the LEADING separators, which
it doesn't.

I've added a small dialplan example to test.
And uploaded a patch I created for latest func_cut.c for Asterisk 1.4
trunk.
The patch should also work on 1.6.2 (with offset) since this part has not
been changed since.
