 /*
! Newsizedstringobject() and newstringobject() try in certain cases
! to share string objects. When the size of the string is zero,
! these routines always return a pointer to the same string object;
! when the size is one, they return a pointer to an already existing
! object if the contents of the string is known. For
! newstringobject() this is always the case, for
! newsizedstringobject() this is the case when the first argument in
! not NULL.
! A common practice to allocate a string and then fill it in or
! change it must be done carefully. It is only allowed to change the
! contents of the string if the obect was gotten from
! newsizedstringobject() with a NULL first argument, because in the
! future these routines may try to do even more sharing of objects.

! must point to a null-terminated string of length `size'.
! 
! The member `op->ob_size' denotes the number of bytes of data in the string, 
! not counting the null terminating character, and is therefore equal to the 
! `size' parameter.
