Documentation: No argument of ALLOC_GROW should have side-effects

Browse Source 
The explanatory comment before the definition of ALLOC_GROW carefully
lists arguments that will be used more than once and thus cannot have
side-effects; a lazy reader might conclude that the arguments not
listed are used only once and side effects safe.

Correct it to list all three arguments, avoiding this confusion.
