Don't warn on lack of bashisms in core bash configuration files!

File patterns like bash_profile, .bash_profile, *.bash_profile, and similar for bash_login, bashrc, may feature bashisms. Or they may happen to not feature bashisms.
But don't warn on the lack of bashisms in such files!
As a workaround, users may specify a POSIX sh shebang at the top of their bash configurations. Though that is really awkward and likely to break as configuration files are tweaked.
