Patch Level: 4
Release Status: release

Description:
        The 'select' directive's syntax does not correspond to the rest of the 
shell's syntax.
        I am not sure if this is by design; if it is, let me know and I'll go 
away.

        The following is valid shell code:

        d=($(ls /usr/src/pkg/*/$1));
        n=${#d[@]};

        if ((n > 1)); then {
            echo "Ambiguous dir specification";
            exit 1;
        }
        else {
            dir=${d[0]};
        } fi;

        cd ${dir} &&
        make clean && {
            make update ||
            make install;
        }
        
        I'd like to replace the first part of the if/else/fi with:

        if ((n > 1)); then {
            select dir in ${d[@]}; do {
                break;
            } done;
        }
        else { ...

        ...but select breaks on the "} done;" syntax that works with, e.g.,

        while sleep 5; do {
            date;
        } done;

        until [ -f ${tmpfile} ]; do {
            sleep 5;
        } done;

        for dir in ${d[@]}; do {
            echo ${dir};
        } done;

        This violates the POLA, from my point of view.

Repeat-By:

        d=($(ls /usr/src/pkg/*/$1));
        select dir in ${d[@]}; do {
            break;
        } done;
