[TxMt] CocoaDialog stalls with stdin

Yep, that works great. But I had to add a "cat - | " to the beginning to
pass stdin. Here is the finished command:

cat - | {
    if [ -f /tmp/tm_saved_regex ]; then
        REGEX="`cat /tmp/tm_saved_regex`";
    else
        REGEX="^\s*\w+.*$";
    fi

    res=$(CocoaDialog inputbox \
        --title "Find matching lines" \
        --informative-text "Regular expression to match lines:" \
        --text "$REGEX" \
        --button1 "Find" --button2 "Cancel")
    [[ $(head -n1 <<<"$res") == "2" ]] && exit_discard
    REGEX=$(tail -n1 <<<"$res");
    
    echo "$REGEX" > /tmp/tm_saved_regex;

    TMP="$(mktemp /tmp/tm_findmatchinglines_XXXXXXXX).${TM_FILENAME##*.}";
    perl -ne "print if /$REGEX/" > "$TMP";
    mate "$TMP"
} &>/dev/null &
