ba9d287fb2 planet_gr: lores version of planet 
apparently this all came from the Acorn User's January 1989 issue,
an article by Peter Voke, called 'A World Of Your Own' (page 85)

72f8e5070f dos33: some more comments to clear up the last fix 
needed to break out Beneath Apple DOS for this one

TSL_OFFSET_L/H says what offset in the file the first TSL entry
is representing. It's a 16-bit sector value.  Apparently not everything
uses this value.

87f7fc15f5 dos33: fix some issues when copying files off disk image 
ran across this when trying to debug a different issue

by default we can only get total sector size from the T/S lists
(which is only a multiple of 256 bytes) but in addition A (basic)
and B (binary) files also tell you the exact length.  So we used that
to truncate to the exact length

Only it turns out some programs (I'm looking at you, cracked version
of WAVY NAVY) intentionally set the file size to be wrong and so
we were truncating things improperly

I think this updated code is a bit more clear.  Hopefully it doesn't
break anything, I need a better test suite.
