Another possibility is to design your own escape convention for trailing white 
space and remove it just before the test.  You could strip backslash just before 
newline, say.  This will be more robust in the presence of tools that routinely 
strip trailing white space.

If you do keep trailing whitespace, please check that it survives editing the 
file by an Emacs configured something like this:

(setq whitespace-action '(auto-cleanup))
(setq whitespace-style '(trailing empty))
(global-whitespace-mode t)

as this is how I edit Emacs source code. I assume you can do this by setting 
local variables in the affected files.
