Newlines in /proc/.../config

The newer Clicks reconstitute the configuration string from a Vector of
arguments. This loses any irrelevant whitespace, replacing it with single
spaces; thus, the missing newlines.

The relevant method is Element::configuration(). This method is here to
stay, I think. The reason: it greatly eases the implementation of generic
read/write handlers like read_positional_handler, read_keyword_handler,
reconfigure_positional_handler, and reconfigure_keyword_handler.

Nevertheless, I understand your problem. Current CVS has changes that will
preserve whitespace when possible.
