Of course there's also the alternative of escaping the newlines out in 
the literal. The replace result above is exactly

"""\
lots of text hundreds of characters long\
more text on another line but we really don't want any line breaks\
in our final string\
so we replace newlines in this multiline string\
with an empty string thus\
"""
