why is there . [dot] in default PATH?

Hi,

This one kinda supprised me.  When I was looking around by new 3.8
install I noticed that in /etc/skel/.profile that PATH contains a . in
it, which I found supprising as I've always assumed that this was not a
sensible thing to do.  I've taken it out as I'm not too happy when
having the current directory in the path.

Any ideas why this is there?

Thanks

Jon
