fmt/1741: signatures with offsets that commence with ranges of wildcards

[richardlehane]

Signatures for this new format have min/max offsets 32768/70468 as well as a starting range {0-16}.

The PRONOM parser is incorrectly reading this as a min/max offset of 0/16.

Probably should resolve to min/max offsets of 32768/103252 [not 70484 as confusingly the PRONOM max offset value is relative to the offset value!]

Ooh that's subtle. Needs fixing upstream for sure

[richardlehane]

sorry I meant siegfried's PRONOM parser!! The DROID report for this one looks OK

[Dclipsham]

I meant think the sig right now just needs tweaking. Without an anchor before the {0-16} its logically just saying Min offset 32768 max offset 70500 so no reason to combine signature constructs to achieve that I think

[richardlehane]

true :)
