* src/options.icc (Positions::Positions): New copy constructor.
(Positions::operator=): New method.
(Options::get_max_keysig_size): Remove method.
* src/options.cc (Options::Options): Initialize _key_positions
trivially.

width explicitly, instead of using Options::get_max_keysig_size.
* src/keyword.h (KeywordExt::init_selchars): Add arguments
use_all_chars, positions.
(KeywordExt::delete_selchars): New declaration.
* src/keyword.cc (KeywordExt::init_selchars): Add arguments
use_all_chars, positions. Remove error message if there are no key
positions.
(KeywordExt::delete_selchars): New method.
