There are two issues:
1) Unparsed output may be used by other programs, in such case user
probably wants parenthesis. So I think that we want _possibility_
to print parenthesis (this may be turned on or off by a flag).
2) Effort is needed to determine when we can omit parenthesis without
changing parse -- you noticed "sin(x+1)", but we also have
"sin(x)$Float" which is quite different than "sin x$Float".

Well, the change is to _printed_ output -- currently unittest package can
not handle this...
