I believe the variable quoting here will break the wget command in the
case where _PROGRESS_OPT="-q --show-progress"

  → wget "-q --show-progress" https://guix.gnu.org/
  wget: invalid option -- ' '
  wget: invalid option -- '-'
  wget: invalid option -- '-'
  wget: invalid option -- 's'
  Usage: wget [OPTION]... [URL]...

  Try `wget --help' for more options.
