Well.. I'm perfectly fine with comparing function pointers to NULL in
this kind of case.. In many cases, I find fp == NULL to be clearer than
!fp, but for the fp != NULL case I would rather not see != NULL.. Not
very consistent, but can't really help with that on this kind of coding
style opinions. Anyway, replacing 0 with NULL is a good change.
