Title: Do not create a select mode default mapping.

In select mode (the variant of visual mode), any printable characters should override the selection (see below `:help v_CTRL-G`), so no such mappings should exist. Limit the default visual mode mapping to visual mode (`:xmap`). (The `(Exchange)` can and should be defined for both.)
