function "ls"

[Sylvestre Ledru]

Hi,

I am thinking about changing the behaviour of the function ls
http://www.scilab.org/product/man/index.php?module=fileio&page=ls.htm

I would like to remove the second input argument for a few reasons:
* security issues. This simple example shows how weak it is :
 ls("*.sci","`echo hacked >/tmp/hmhm`")

* Compatiblity and portability. A user working under Linux and using
tricks on this function won't have the same result under proprietary
operating systems.

* We are too closely related to the ls behaviour on the platform

* The code could be directly pluged to the listfiles and therefore
facilitate the maintenance (It is already the case under Windows).

Any objections ?
