One possibility is to use -c 'CSS_LINES=....' to replace completly the
output related to css.  Then --css-ref and --css-include output is
replaced in that case so those options will not have an effect.

Indeed, in addition to removing the CSS lines, it removes class
definitions (and probably only some classes, not all).  Maybe the best
would be to remove NO_CSS completly and document that -c 'CSS_LINES='
can be used to remove/redefine CSS completly?  Currently the
documentation on NO_CSS/CSS_LINES is very short.


The current implementation in makeinfo is complicated, but I can't see
another way to achieve the possibility to add to makeinfo CSS rules in
other way.  Suggestions welcomed, but they should preserve the level of
customizability.
