You don't need to break at path boundaries -- Berthold was just trying
to show you the cleanest looking way to do it.

[1] Python will automatically concatenate adjacent strings.
[2] Python will join lines that, according to the grammar, are obviously
    incomplete, so you can split lists, tuples, dicts and parenthesised
    expressions (like arg lists) over several lines without an ending
    backslash.

So there are a number of line continuation styles you can choose from:

>>> "abc" \
... "def" \
... "ghi"
'abcdefghi'

>>> ( "abc"
...   "def"
...   "ghi" )
'abcdefghi'

>>> """abc\
... def\
... ghi"""
'abcdefghi'

(and I'm sure there are more... )
