[PATCH 10/11] pragma once: delete few backslashes

Subject: [PATCH 10/11] pragma once: delete few backslashes

Some macros contain one backslash too many and end up being the last
macro in a header file. When #pragma once conversion script truncates
the last #endif and whitespace before it, such backslash triggers
a warning about "OMG file ends up in a backslash-newline".

Needless to say I don't want to handle another case in my script,
so delete useless backslashes instead.

It looks plausibly correct, but the commit message ought to mention it.

Probably should use do{}while(0) trick.
