I've looked the code and proposed patch, and found two problems.
First, mfgets() function can not be used to read a line anymore if you
are willing to allow arbitrary amount of white-space characters to
appear; it returns null-terminated strings while PDF spec. allows
null characters to appear anywhere within a line since they are
simply kind of white-space characters in PDF.
Next, garbage after valid data is not detected since it simply does
sscanf() and does not check the data unread.
The second problem is also in the original code. But, If you think
that arbitrary amount of white-space characters (including empty
lines) can be inserted between each pieces of xref data and xref
subsections, as oppose to current implementation, you need to do
more works to be consistent.
