Is this how it's typically done?  I thought that sourcing .profile, say,
from .bashrc would destroy the purpose of having a separate thing for
when logging in and another for interactive runs of the shell.  Now
realize I could make a library-script and source it from both scripts
(.profile and .bashrc), but then I've never done that myself and so I
was wondering how people do things.

Anyway, thanks very much for sharing your side of things!
