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:
- 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
