[PD] Patch acting weird with Pd 0.46.6

[Pierre Massat]

Dear list,

I just ran into something very odd while trying to parse a string to
extract a filename from a path with [list fromsymbol].
Please look at the patch attached. I try to loop backward through the
fields of a line in a [text] object to find the first "/" (code 47).

When I do it "manually" (load the list and get the last field, then
decrease the counter with a bang until I reach the last "/", everything
works fine, and the counter starts at 17 and goes down.

But when I try to automate it by checking if the output equals 47 and by
sending a bang to my counter when it's not, I get a very strange result.
The counter actually starts at the last occurrence of "/" (47) in field 8,
and then goes up to 17.

I am probably very tired and I must be missing something obvious. But right
now this looks like aliens have hacked into Pd and are playing with my
nerves.

Thanks in advance for your help,
Pierre.

PS : I've been using the new text and array objects and I think they're
very useful, though not always super intuitive.
