grc.sh in newmaster branch breaks some stuff

[LFd3v]

Hi, there.

Thank you for creating and maintaining grc.

When trying to use the newmaster branch I noticed that I could not start tmux anymore, it would always close with [exited]. After a long troubleshooting, I found the culprit: the command exit in L7 of the grc.sh file (added in 33942c1).

grc/grc.sh

Line 7 in 33942c1

[ -n "$BASH_VERSION" ] || exit 0

After changing it to return, like used elsewhere in the file, I could use tmux normally.

Just for the record, I also added some code to avoid creating aliases for command that do not exist, as well we including the old alias when creating the new one (this fixed a problem with ls not using color for the filenames).

    for name in ${cmds[@]}; do
        if command -v $name &>/dev/null; then
            if type $name | grep -q alias; then
                alias $name="colourify ${BASH_ALIASES[$name]}"
            else
                alias $name="colourify $name"
            fi
        fi
    done

Thanks again.

Regards
