We can't know how many bytes fgets() read when we reach EOF and fgets() didn't see a newline; we can only assume that at least strlen(buf) bytes were read. This is quite obnoxious if one wants to use NULs in raw input, but at least we can make reading "a\0b\0c\0" with no newline yield "a\0b\0c", losing only the final sequence of NULs. We can't use getline() either, since it will want to allocate a buffer big enough for an entire line, and we might not have any newlines in our input. A complete fix will have to use getc() or read(), preferably the latter.
