Ex 5 06: Reimplement getline using pointers

Ex 5 06 asks me to 'rewrite appropriate programs from earlier chapters
and exercises with pointers instead of array indexing'. Suggestions
include: getline, atoi, itoa, reverse, strindex, getop.

Here I rewrite getline using pointers. I don't love this way of doing it
because it still uses an index variable. I'll try another approach.
