[PATCH 2/3] config: Change output of --get-regexp for valueless keys

[Frank Lichtenheld <frank@lichtenheld.de>]

Print no space after the name of a key without value.
Otherwise keys without values are printed exactly the
same as keys with empty values.

 I hope that nobody depends on this specific behaviour.
 Backwards compatibilty would be a pain here, since the --null
 patch would get really complicated
