#2 progen disregards linked dirs

[Sinisa Segvic]

In traversing the given directory path, progen does not
follow soft links, which is not what I would want.
Perhaps there is a reason for that, but I can not see it.

Currently, I am happy with a version in which
I have just deleted the part which checks for a link.

< if ( $descend && -d $p && ! -l $p ) {

> if ( $descend && -d $p ) {

Perhaps one could add a command line option
specifying the desired behaviour.
