Yes it is.  Currently backslash-horizontal space(s)-newline is removed
from the input, no matter what the context.  Here newline can be '\r'
'\n' '\r\n' or '\n\r'.

Jamie, when your paperwork finishes could you please use
skip_escped_newlines () in your skip_line_comment patch so we stay
consistent here?

Thanks,

Neil.
