Example:
When the second argument of the push_shift function is negative, the shift is to the right.
So, if m is the EStackIndex at the bolded tag in the string "goodbye" as follows
0 g o o d b y e 0 STR_DATA_TAG
then
push_shift (m, IntegerMinus1Index);
pushes the right shifted string " goodby" onto the estack such that top_estack points to the
bolded tag as follows.
0 ï g o o d b y 0 STR_DATA_TAG
