I do get the warning above with -Wall, but not without.  However,
if the \<space> is not in a comment, I get this:

backslash.c:3:1: warning: backslash and newline separated by space

which is much nicer and appears with or without -Wall.  It's the
same processing phase, so the message should be consistent, right?:)
