wstockandClaude Opus 5.5 3af350026f Issue #2366: a /Prev reference to an object holding the offset reads that offset ...

iText's indirectPrev.pdf writes /Prev 6 0 R, and object 6, listed in the
same update, holds 470, the offset of the first section. Both readers took
the object number as the offset, so cos found no section at 6, rebuilt the
file from object headers and lost its revision list, and hayro's chain
stopped there.

When /Prev is a reference, the sections read so far (cos) or the section's
own entries (hayro, which now reads them before following /Prev) are asked
for that object first. If it holds a non-negative integer, that is the
offset; otherwise the object number still is, as the tiff2pdf files need.
