Well, this was a reduced example from a tex file, that I could not
reformat, because a comment started with %%. I expect even the endpart
of a comment to be reformatable according to the current &tw setting.

Well, have you tried it with a complete three-piece comment? Latex Files
are a good example:
(taken from $VIMRUNTIME/ftplugin/initex.vim)

vim -u NONE -N --cmd ':set comments=sO:%\ -,mO:%\ \ ,eO:%%,:% tw=20' -c
'call setline(1, "%% ".repeat("foobar ", 10))' -c 'norm! Vgq'

(still does not reformat).
