2b might be simpler in the short run, but will it be in the long run?
Or are you assuming that libc getline won't ever change much?

It could do so conditionally.  For example, it might use the
stdio_ext.h interface on Solaris.

However, you're the expert here, and if you've judged that 2b)
is less work overall, perhaps we should just do that.  We can
always switch to 2a) later if need be.
