1. Support almost arbitrary characters in dir names …

   dconf itself places minimal restrictions on key paths.
   `dconf_is_key` and `dconf_is_dir` just stipulate the following:
   
   - Path must start with `/`.
   - Path must not contain `//`.
   - Key paths must not end with `/`.
   - Directory paths must end with `/`.
   
   So in theory, they can all contain special characters like `[]*#@`.
   In practice, `dconf dump` will fail to print paths containing `[` or `]`
   due to limitations of `GKeyFile` enforced by `g_key_file_is_group_name`
   so those or control characters will not really appear in input of dconf2nix.
   But it can still contain all other kinds of characters including spaces
   at the start or end.
   
   Since the spaces are now preserved as expected, we need to remove them
   from the test cases (not sure how they got there). Also clean up the
   duplicate dirs/groups.
   
   Keys have slightly tighter restrictions introduced by `g_key_file_is_key_name`.
   Whitespace is only allowed in the middle of a key and `=` is not allowed at all.
   `[` and `]` are not allowed either, except at the end in a subkey suffix,
   which has further restrictions. But I doubt anyone will want special
   characters in keys so I am only extending it with an underscore.
