Same here, but I made it return the number of characters read so that
it can also avoid the strlen() call (which will be incorrect anyway
if there were any nulls in the line).  Why does any function return a
pointer that you obviously already knew?  Seems like it would only
be useful if you wanted to nest function calls and ignore errors.
