quoting of operators like diff and integrate



diff(u,v) is 0
'diff(u,v) is  'diff(u,v,1)   or some 2-d version of that.

integrate(u,v) is   u*v
'integrate(u,v) is   u*v.   By analogy with the above, shouldn't it be 
'integrate(u,v) ?

This makes it nearly impossible to do something like
   tellsimp ('integrate(u,v), ....),  because the first argument becomes 
u*v.

Bug?  If not, how would you produce  the noun form of integrate(u,v)?  
'(integrate(u,v))  quotes the verb form.
