Add text to history with shell integration

[asmeurer]

It would be useful to save the input text to the shell history with shell integration. This can be done by modifying the shell function like

_sgpt_bash() {
if [[ -n "$READLINE_LINE" ]]; then
    history -s "# $READLINE_LINE"
	READLINE_LINE=$(sgpt --shell <<< "$READLINE_LINE")
    READLINE_POINT=${#READLINE_LINE}
fi
}

Happy to make a PR for this if you agree.

I'm now using a slightly modified version, which prevents duplicate # from re-executing the same prompt

_sgpt_bash() {
if [[ -n "$READLINE_LINE" ]]; then
    # Remove any leading # and space characters
    READLINE_LINE=${READLINE_LINE##\#*([[:space:]])}
    history -s "# $READLINE_LINE"
	READLINE_LINE=$(sgpt --shell <<< "$READLINE_LINE")
    READLINE_POINT=${#READLINE_LINE}
fi
}

Also I think it would be better to store this function in a separate file and only add a line to bashrc sourcing that file, that way it is easy to update the script in future versions.
