`${SHELL##*/}` depends on user configuration; `${0##*[-/]}` does not

[LucasLarson]

The scripts below appear shell-agnostic, but if running them using Bash on a system whose ${SHELL} is Zsh, they don’t work at all.

For example, instead of:

. "${HOME}/.${SHELL##*/}rc" && exec "${SHELL##*/}" --login

we should use:

. "${HOME}/.${0##*[-/]}rc" && exec "${0##*[-/]}" --login
