Here's how I do it.  Use C-h k <keyseq> to get the help for a key
sequence.  Then use the kbd macro with the text representation of key
sequence that C-h k gave.  E.g. when I do C-h k C-c C-SPC, I get a
message saying "C-c C-SPC is undefined" (if it was defined, I'd get a
help buffer with the same text representation of the key sequence).
So I could do (global-set-key (kbd "C-c C-SPC") 'some-command) to
define it.  I can't think of any key sequences that this has not
worked with, and I'm fairly certain that this is the same
representation that ends up in the lossage buffer.

(define-key your-keymap (kbd "C-SPC") 'delete-trailing-whitespace)
