The problem is that docstrings describe the behavior of a specific
function, so they usually don't mention the more general aspects that
affect all functions of a given subsystem, such as here the general
treatment of the empty string when used as a file name.
Otherwise, every file-name-manipulating function would have to repeat
this information in its docstring.
