Hi, I assume . command does not search current directory anymore in bash 4 for a reason. Perhaps it is specified by relevant standard, although I did not find it.
This incompatible change affects me a lot. I imagine I am not alone with this. To forestall questions from users like me, consider adding information about it to this file: http://tiswww.case.edu/php/chet/bash/COMPAT Thanks. -- vda
