search: print package name once with NO_COLOR

[AladW]

Issue #995

Alternative: always print the hyperlink, even with NO_COLOR=1. The hyperlink function is then reduced to:

hyperlink() {
    local OSC8="\e]8" ST="\e\\"
    printf "$OSC8;;%s$ST%s$OSC8;;$ST" "$1" "$2"
}

There's really not much point in using variables here

Maybe not, but at least in the alternative example it identifies the escape sequences.
