"Even in a raw literal, quotes can be escaped with a backslash, but the "
"backslash remains in the result; for example, ``r\"\\\"\"`` is a valid "
"string literal consisting of two characters: a backslash and a double quote; "
"``r\"\\\"`` is not a valid string literal (even a raw string cannot end in "
"an odd number of backslashes). Specifically, *a raw literal cannot end in a "
"single backslash* (since the backslash would escape the following quote "
"character). Note also that a single backslash followed by a newline is "
"interpreted as those two characters as part of the literal, *not* as a line "
"continuation."
