NAME
    CPAN::HandleConfig - internal configuration handling for CPAN.pm

  "CLASS->safe_quote ITEM"
    Quotes an item to become safe against spaces in shell interpolation. An item is enclosed in
    double quotes if:

      - the item contains spaces in the middle
      - the item does not start with a quote

    This happens to avoid shell interpolation problems when whitespace is present in directory
    names.

    This method uses "commands_quote" to determine the correct quote. If "commands_quote" is a
    space, no quoting will take place.

    if it starts and ends with the same quote character: leave it as it is

    if it contains no whitespace: leave it as it is

    if it contains whitespace, then

    if it contains quotes: better leave it as it is

    else: quote it with the correct quote type for the box we're on
