substr(string,start,end) doesn't mimic the cl when start is zero.

Description (Last modified by rij) 

Under the cl:
tables> =tabpar.value
0
tables> =substr(tabpar.value,0,1)

Under PyRAF:
--> iraf.tabpar.value
'0'
--> substr(iraf.tabpar.value,0,1)
'0'

The iraf substring is interpreted as a Python substring by subtracting 1 from the start index. However, under Python, -1 has a different meaning as an array index from 0 under the cl. Just need to trap this.
