doc: don't return -1 from main in manpage examples

It is custom for C functions to return a negative integer to denote an error. This should not be done with main() though, as the return value is used as an exit code, which is a byte (unsigned char), so return -1 becomes 255, which is unconventional. Fix examples where main returns -1 to return 1.
