Could easily be changed, but I'd like to understand it first. I cannot
reproduce the problem. I never have `.' in my PATH and when I do

        cat > foo
        echo I am here
        CTRL-D
        . foo

I get "I am here".

Of course, this happens on Debian GNU/Linux. Is this a system-specific
problem or feature?
