This is even more robust:

_show_ambiguity_end()
{
  local prefix=${${compstate[unambiguous]}[1,${compstate[unambiguous_cursor]}-1]}
  if [ -n $prefix ]
  then
    [ ${compstate[quoting]} ] && prefix=${prefix[2,-1]} || prefix=${prefix:Q}
    [ "$curtag" = "all-files" ] && prefix=${prefix##*/}
    [ ${compstate[quoting]} ] || prefix=${prefix:q}
    ZLS_COLORS+=":=(#b)${prefix//?/?}(?|)*==4"
  fi
}

It actually works by matching the string length instead.
The quoting/unquoting is performed only to correctly strip the directory name.
