loc-create: ignore spaces in descriptions that come from code indentation

[michbarsinai]

Currently, if the code of the policy space is indented, the whitespace used for indentation is added to the space item's description in the created localization. Instead, the description should become the short version (2nd line in the localization), and the extra spaces need to be removed.
