At least in Mac OS X and Linux fgets works just fine: it reads bytes
until it sees \n, as promised in its man page. Unfortunately, fgets does
not tell you how many bytes it has read and you're left with having to
call strlen to find this out. I guess we could avoid strlen and use
memchr instead.

How did you propose to replace fgets?
