Ex 5 12: Change command line args to entab
Ex 5 12: Change command line args to entab

Ex 5 12 asks me to make entab and detab accept arguments of the form '-n
+m' specifying a tab offset n and a tab increment m. I found this very
difficult. The main issues were getting the multidimensional pointer
arithmetic correct in the argument handling and debugging confusing
segmentation faults. I discovered the limitations of printf statements
and used gdb to diagnose some problems.
