CPAN::HandleConfig − internal configuration handling for CPAN.pm
Quotes an item to become safe against spaces in shell interpolation. An item is enclosed in double quotes if:
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
