comment-start redefined in cc-langs.el

[martin rudalics]

With emacs -Q do

C-h v comment-start RET

gets me

comment-start is a variable defined in `newcomment.el'
...

Now load cc-mode in a new buffer, return to scratch, and do again

C-h v comment-start RET

gets me

comment-start is a variable defined in `cc-engine.el'
...

If I now click on `cc-engine.el' I am told

find-function-search-for-symbol: Cannot find definition of `comment-start' in 
library `cc-engine.el'

The same holds for `comment-end' and `comment-start-skip'.

Would it be possible to rename these to `c-comment-start',
`c-comment-end', and `c-comment-start-skip' in `cc-langs.el'?
