WARNS fixes:

1) Add missing parens around assignment that is compared to zero.
2) Make some variables that only take non-negative values unsigned.
3) Some casts/type changes to fix other constness warnings.
4) Make one variable a const char *.
5) Make sure termwidth is positive, it doesn't make sense for it to be negative.
