Yep, the is the intended/correct behavior of PHYSFS_openAppend.
Also note, you should be using 64-bit type specifiers in your
printf statements. For Win32 (MSVC) it is %I64d, for GCC use %lld,
I typically just have a define like I64FMT for this so you don't
have to duplicate code.

P.S. This is what part of the alphabet would look like if Q & R were eliminated.
