But my point is that they are all eventually processed by
`read_c_string_or_comment' later, which takes care of backslash
continuation no matter it is the very first thing in the string or in
the middle of it.

The old code is simply enforcing doc string to begin with the line
continuation.  Anything else is rejected.
