3f43a16bc63 ; Avoid byte-compilation warning in c-ts-mode.el

Originally our c-ts-mode--anchor-prev-sibling only specially handled
labeled_statements, now we add special case for preproc in the similar
fasion: instead of using the preproc directive as anchor, use the last
statement in that preproc as the anchor. Thus effectively ignore the
preproc.

There should be an accompanying test, but there are some problem in
the elif preproc directive indent so it would pass, we'll add the test
when that is fixed.

* lisp/progmodes/c-ts-mode.el:
(c-ts-mode--anchor-prev-sibling): Add special case for preproc
directives.

* lisp/progmodes/c-ts-mode.el (c-ts-mode-set-modeline): Remove
trailing blank from comment-start when indicating the comment
style on the mode line.

This fixes a bug that miscompiled

  (cond ... C S1...Sn)

where S1...Sn are switch clauses (that can be compiled into a switch
op) and C a non-switch clause, by tucking on an extra copy of C at the
end.  This was a serious wrong-code bug when the condition of C had
side-effects; otherwise it was only a waste of time and space.
