The backslash is there. Try
function.__doc__
to see it. The "problem" is that docstrings are run through
a detex'ing procedure before being displayed. I don't remember
is there is a way to make that detexing show backslashes.
The detex function is in devel/sage/sage/misc/sagedoc.py.
Looking at it we see that if you do this instead you'll see the backslash:
def function(x, str=''):
r"""nodetex
The string str could be a LaTeX command like '\vspace{3em}'.
"""
return None
