"echo" literally in sh scripts (was: why would "tr --complement --squeeze-repeats ..." append the substitution char once more? ...)

Interesting.  I used the following instead:

    bugit_echo () {
        # POSIX `echo` has all kinds of "features" we don't want, such as
        # handling of \c and -n.
        cat <<ENDDOC
    $*
    ENDDOC
    }
