more is wrapping the lines

I found the below function online (thanks to whoever wrote it}. The problem seems to be more is wrapping the output. I like the option to view output page by page but do not like wrapping. How can I change to no line wrapping but allow for scrolling the output like less or more commands?

#  Find a pattern in a set of files and highlight them:
#+ (needs a recent version of egrep).
function fstr()
{
    OPTIND=1
    local mycase=""
    local usage="fstr: find string in files.
Usage: fstr [-i] "pattern" ["filename pattern"] "
    while getopts :it opt
    do
        case "$opt" in
           i) mycase="-i " ;;
           *) echo "$usage"; return ;;
        esac
    done
    shift $(( $OPTIND - 1 ))
    if [ "$#" -lt 1 ]; then
        echo "$usage"
        return;
    fi
    find . -type f -name "${2:-*}" -print0 | 
xargs -0 egrep --color=always -sn ${case} "$1" 2>&- | more

}
