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.
