PEP 257 Not respected

[charlie-rivos]

Docstrings are defined in PEP 257 as "A docstring is a string literal that occurs as the first statement in a module, function, class, or method definition." When reuse adds a header, it forcibly adds a space before the docstring violating this principle.

When the style is set to Python and the first line in the file is a docstring, a space should not be added between the license and the docstring.
